My husband and I put a new master cylinder in this vehicle recently. We bled the system but there is still excessive pedal travel. We tried bleeding the system again and had the same results. There are no apparent leaks in the brake system.
View 10 RepliesI own a 2003 Toyota Camry SE four cylinder sedan with only 46,000 miles. The car has four wheel disc brakes and an anti-skid braking system. About a year ago, I started to notice that there was excessive travel in the brake pedal. That is, the pedal will travel an excessive distance before there is any braking action. I have tried to correct the problem by pumping the brakes as I back out of my driveway to engage the self-adjusting mechanism; doesn't work. I have also gotten in the habit now of pumping the brake pedal; that works a little, but it's not a solution. Being an old chap who always maintained my car myself, and diagnosed and repaired most problems, I concluded that the problem was the master cylinder because when stopped at a light, the brake pedal would continue to go down. Incidentally, there has been no loss of brake fluid since I bought the car new in 2003. Recently, I had the master cylinder replaced and learned that I'm not as car-smart as I thought. There is no improvement in the pedal travel problem.

When I use my brakes at low speeds under 15 mph, there is a bit of extra brake travel before they engage properly ...
Is this normal? You can hear the air coming out.
The reason I ask if it's normal is because it seems like I have to press my brake pedal halfway down before it engages. At least an inch or two. However I can still lock up the beaks. But it seems like they are not as sensitive. Takes a bit of travel to engage.
I've already bled the brakes too.
New to me 2002 F-250 PSD, done brakes all the way around for piece of mind.
Job went very well, replaced one caliper and its bracket, serviced all pins and replaced one set of pins as well, (different corner). Bled brakes all day via gravity, watching reservoir and filling as needed as to flush in new fluid. Truck is in great shape. Mileage 153,000 no rust, turned all rotors just to re-surface.
Now here is what's happened, my pedal is good but it pulses in the first 1/2 inch of travel and once passed that no pulse, got under and watched the pedal rod do this as I very easily touched it in that first 1/2 inch of travel, you don't even begin to get much brake started here if any! Truck running; yes-Truck not running no pulse action occurs.
I'll add this: fluid removed had a green tint to it but had no moisture or bad odor. Different fluid??? I didn't know. Used Dot 3 Off the shelf O'Reilly's.
Hydro-booster didn't like fluid? Air? Master cylinder? No leaks before or after this procedure.
So I finally towed our new to us travel trailer home tonight and the spot I created at my house to park it in required a lot of backing to get it shoe-horned in its place. As I was almost finished I smelled a burning smell and my wife said she saw some smoke from under the hood. I had neglected to look at my newly installed trans temp gauge during all the maneuvering as I was watching my mirror and the trailer so closely.
The gauge had reached ~180F and it was only about 55F outside. I know this violated the ambient plus 100 rule, so I allowed it to idle and cool down to 140 or less. When I got the trailer unhooked and the Ex back in the garage I crawled under it and the smell was definitely burnt tranny fluid and it was coming from the front of the bell housing or the access hole for the torque converter, not 100% sure.
So my question is, have I toasted my tranny, or was it just a mild overheat situation and it will recover just fine? If I am towing and the trans temp gets above 180 again will it start leaking most likely? Is it just something like a pump seal that I could drop the tranny and replace relatively easily, or have I most likely done internal damage. Hoping I did not just cost myself a tranny build on a truck with only 73k miles :-(.
I have a 2001 Civic LX; I would like the clutch pedal travel distance to be far less than it is.
As in most manual cars, I find that the clutch pedal travel is mostly useless. That is, once the clutch is fully engaged, the pedal still has a goodly way to go before it hits the stop. On pedal depression the inverse is true. As modern hydraulic clutches are self-adjusting, this once-necessary extra distance is pointless.
(I would rather clutch with my ankle than my whole leg. If I could cut the pedal travel in half (or more), I would like that very much.) Is this possible? How would I do such a thing?
So I just had my entire clutch replaced while another repair was taking place. What I've noticed is the "clutch engagement" has changed. Where as I would have the clutch start to engage/disengage at the 1/2 way point on the pedal travel is now the last 1/4 of the pedal. Is this a "normal reaction to a new clutch that just takes getting used to or is there an adjustment I can fine turn it with? Do I just have to wait for it to "break in"? When I replaced the clutch on my dearly departed 94 ranger, I replaced the bearings & disc only reusing the pressure plate and did not have this issue.
View 3 RepliesI took delivery last week of a new 2012 F250 with a 6.7 Power Stroke Diesel. This is my third F250 with a Power Stroke Diesel. My first one was a 1997 w/7.3 PSD and my last one was 2001 w/7.3 PSD which I traded in for the 2012.
Now for my problem. The brakes seem spongy to me. When I am applying the brakes I get what seems like a longer than normal pedal travel (to me anyway) and soft. The braking isn't as good as my last two F250's. If I pump the brakes, the brake pedal firms up and the braking really improves. I have not contacted my dealer yet.
My clutch pedal has started squeaking every time I step on it (seems to work fine otherwise). If I hit it with WD-40, is there any risk of lubricating something that shouldn't be lubricated?
View 2 RepliesI have a 2003 F-150 supercrew 4x4, was having problems with the brake pedal going to the floor, had replaced the front calipers, master cylinder and the brake booster. I have blead everything out including the rear calipers even though I didn`t touch them, the truck stops but the pedal isn't what it used to be, even when the truck is off the pedal has a tendency to go down, there is nothing leaking and not losing fluid, don`t know what else to do?
View 3 RepliesI just finished replacing pads, calipers, rotors, wheel cylinders & brake drum hardware on my truck along with flushing the brake fluid. The brakes work but the pedal goes almost to the floor. While bleeding them some air did come out as expected. But a couple times the master cylinder reservoir got very low on fluid. The workshop manual talks about bleeding the MC but are special fittings needed for that?
View 10 RepliesI have a 1998 F 150 extended cab and the brake pedal is low. The front calipers and rotors were replaced last year because the left front caliper froze on and smoked the pads. I also replaced the brake booster and master cylinder because the brake booster showed signs of leaking vacuum. The whole system has been bled completely twice. After each bleed, the pedal was high and firm.
I have not found any sign of leakage and the fluid level looks ok and unchanged. The rear brakes look ok, but no work on them in last few years. Mileage is 198k. I had to hit the brakes hard on a muddy road a few weeks ago and the truck stopped straight, so the ABS seems ok. The problem is that the pedal has dropped down a few inches from where it was then the system was bled out. What to check next?
The brake pedal intermittently goes to the floor on my nephew's 2003 F150 without grabbing at all. Pumping the brakes restores them, then they act normally for a while. I've replaced the master cylinder with a new Motorcraft unit, no change. No ABS codes. All rubber lines are in good shape. I'm stumped, although I suspect the ABS system somehow. I'm going to have him pull the ABS fuse and see if the problem goes away.
View 6 Replies2002 F-150 4x4 w/ 5.4 v-8. Brake pedal goes half way to floor before it starts to stop the vehicle. I have replaced and bled the master cylinder, bled out all of the calipers, and the calipers are installed correctly because the bleeder screws are at the top on all of them so no air can be trapped up there. The truck seems to stop fine, but just takes more pedal to get it to start stopping than I'm comfortable with. Could the ABS unit need bled out too? Or could it be an adjustment issue with the booster rod?
Also, something else I noticed, and it may be related..the ABS unit usually makes a slight clanking sound (like someone kicking a metal garbage can) a couple seconds after the key is turned on. I know its the ABS unit because a couple weeks ago I had a friends scanner hooked up to the truck, and I went into the ABS computer to clear the codes (have ABS light on from what I found to be a bad sensor wire on the front drivers side according to the scanner) and as soon as i cleared the codes on the ABS, it made that sound. I don't know if maybe there is something wrong with the ABS actuator, or if it's related to the brake pedal issue.
I recently purchased a mutt of truck, a 97' F150 heritage w/5.4 Triton motor, 1/2 ton 2WD short bed.
Having a brake issue, the pedal keeps fading. I noticed it first while sitting in traffic on a down hill grade. I am holding the pedal and notice it starts to creep down slowly, I pump it up and it firms up then starts collapsing again. So general logic says hydraulics are loosing pressure right?....No leaks anywhere, so it must MC tight?
I have replaced the master cylinder, brake booster, and both rear wheel cylinders. Long story short they all needed it, truck has 265K+ on the body with 95K on the motor. The only thing I did not do by standard is bleed the MC on the bench, I installed and long bled starting with the right rear working my from longest distance to shortest (wheel speaking). So when bleeding I did of course get air coming out because of the new parts but I still have the same fade issue.
I am confident there is no air in the lines, I have bleed a quart of brake fluid through just to be sure. I have read a lot about proportioning valves and ABS stuff.
I will try and get some vehicle specific photos and attach have hit a road block with this. I am leaning towards the ABS valve thingy mounted on the drivers fender that has four lines attached (2 in and 2 out). Other than that it comes down to hard lines which have no leaks.
I have a 2000 SCrew KR F150. A couple of weeks ago I noticed the brake pedal was slowly going to the floor while at a red light. I pulled over and popped the hood checked the fluid reservoir. It was full, so obviously no wheel cylinder issues or fluid loss. I haven't had a chance to tear into it yet.
View 14 RepliesAfter replacing my brake pads and shoes I am hearing a squealing noise coming from the area near my brake pedal. This noise sometimes becomes high pitched if I depress the brake too hard. I am also losing a little bit of brake fluid if I depress the pedal hard several times. The brakes themselves function fine and have no problem stopping. When I bled the brakes today some of the fluid was black. I figured it might be air in the system but after bleeding them it is still happening. I also replaced the bleeder screws.
1997 Pontiac Sunfire 2.4L uses DOT 3 brake fluid.
The brake lights come on in the rear after i park the car. it appears the brake pedal is not springing back for enough to disengage the brake lights. It does not do this all the time, but seems to have start doing this at night when it gets colder. I can look outside and see my brake lights on, then go off, then come back on. It has made the battery go dead twice in the last week. is this a easy fix or something more complicated. this has nothing to do with parking brake, i normally do engage parking brake since i park on a flat surface road in front of my home.
View 6 RepliesI have a 99 f150 and it won't shift out of park. The taillights work and I tried to turn the key forward and move shifter to neutral but it didn't work. Is it the switch on the brake pedal or the interlock solenoid by the shifter?
View 12 RepliesI just joined as I bought my '97 F-150 5.4 4X4 about 3 months ago. The dealer gave me a 6 month warranty but hasn't honored it at all and I've had one problem after another. That's another story though but right now I'm just trying to fix the important issues. The problem at hand are my brakes.
I was noticing a couple days ago (maybe I never noticed it that much as it was a new vehicle to me) that when I apply the brakes it sounds like a bicycle pump and the pedal travels nearly all the way down. It doesn't hit the firewall but I'd probably guess it has 3 more inches or less until it bottoms out. The hissing only occurs as the pedal travels and stops when the brake pedal isn't moving.
Now I'm not sure if the hissing sound is normal as I replaced the brake booster (from the junkyard though) and the new one still hisses when I apply brakes. The brakes seem to work okay, could be more sensitive it's just the pedal feels soft until it almost bottoms out like I stated before and the the brakes grab a little bit harder. What could it be?
