View 10 RepliesI have a 1994 F-250 4x4 w/manual transmission. I was driving a few days ago when the brake pedal suddenly went to the floor. I had almost no brakes (less than 10% at most), but luckily was able to get off the road safely. It was immediately apparent that the line connecting the T-fitting and the passenger side drum had broken.
I have never blown a brake line before, but I always assumed that you would have either front or rear brakes, depending on which line blew. Unfortunately I was wrong! The master cylinder reservoir was about 3/4 full when I initially checked it, but after I moved (slowly) the truck to a safer spot in the parking lot, I checked again and it was nearly empty.
Is my brake system behaving normally (no brakes front or rear, blown line completely empties the reservoir), or should there be some safety factor built in? If the system is operating correctly, is there any way to convert to a system that doesn't give out fully when a line is blown?
I had a leaky brake line behind the gas tank on my 2000 f250 superduty and in the process of fixing that I ended up changing all my calipers and brakes. I've bled the lines and there is no air left in the lines but the brakes are still soft is there something else that needs to be bled. I think all brake fluid leaked on the floor when the line broke.
View 10 RepliesRear steel brake line ruptured the other day (was pretty rusty). Despite being an idiot in regards to automotive repair (among many other things), I decided to give it a shot. I was able to get the damaged section off, went to Autozone with the broken piece, they matched it up, were nice enough to cut it and put on one larger fitting (because the two were different sizes) and flare it for me.
I was able to get the one side (at the T fitting) on OK. That was the "new" side, the one they flared at Autozone. Looks good. No leaks.
The stock side, at the passenger side caliper, leaks like crazy. Not out the threads, but out the hole through which the line passes. Know what I mean?
I'm having a hard time figuring out what's happening, because I'm not sure how this thing works. Does the line fit flush to something inside the connection at the caliper? Is it a bad flare?
It did not go in easy, but the new one was just as much trouble as the fitting that came out (stock?), so it must be right.
The brake line on the passengers side went bad. Called ford for replacement and they said ford is not supplying that line any more. Where I can get a replacement? Its hard line and connects to the rubber line.
View 2 RepliesSo it looks like there is no adjustment on the Parking Brake on this ride other than adjusting the shoes up. As far as I can see my Parking Brake should work like a champ, but it won't hold on much of a hill. I have new shoes, new drums and it is adjusted up so I can hear them drag. I can actually feel it getting tight then looser as you spin the wheel, like one of the new drums is slightly out of round, so I don't think I could go much tighter. Is it possible one or more of the cables is stretched? I did see the shoes spread when I had the drums off and I stepped on the Park Brake, so I know things are working at least that much.
View 2 RepliesI have a 2000 F350 4X4 with a V10 under the hood and a 5 speed manual transmission. It has a heavy western hauler bed, and a dual tired rearend. The truck has disc brakes all the way around that work great. I bought the truck used and immediately replaced all the disc brake pads as well as the seperate parking brake shoes and I had the parking brake drums turned. My problem is the parking brake shoes won't hold the truck at all and never have even when they were new. The parking brake shoes seem very small to me for a truck this size and weight. I have adjusted them as tight as I can with out causing them to drag when they are released. Is this a common problem for this type of parking brake on this type of truck? Is there something I am over looking or need to do to perhaps improve the parking brake? Would it be possible to splice some sort of "locking" valve into the brake lines going to the disc brakes to perhaps hold them engaged when I park the truck? I have a good idea how air brakes work, so I suppose this "locking" valve would work like that except basically opposite of a locking air brake valve, if that makes any sense.
View 14 RepliesI have a '99 E350 van that I am feeling a light anti-lock brake pulse in the pedal when I am rolling to a slow stop under light braking. Braking doesn't seem to be affected, but it doesn't feel right. I tried locking up the brakes and didn't feel any anti-lock pulse...seems backwards.
View 1 RepliesWhat would cause the rear drum brakes to lock up upon hard braking? I have replaced the wheel cylinders, installed new spring kit, and adjusters.
View 9 RepliesInitially when I start driving, the brakes work just find. But it seems as I use the brakes, the front brakes build up pressure and slowly start to lock up. They don't lock up completely, but they do cause a significant amount of drag. The rotor, calipers, rubber hoses and master cylinder are all very new. I'm thinking maybe the issue is with the master cylinder and am considering going to get one along with a brake booster(since it doesn't have one currently).
View 14 RepliesMy rear brakes lock up constantly. It doesn't matter how easy I am on the peddle. The ABS goes through it's test on start up. Afterwards, the light goes out. The vehicle sat for quite a long time. I pulled the rear drums and inspected for rust and brake shoe condition. There was no rust to be found and the shoes seemed to be in good shape. I've read on here about some shoes retaining moisture and causing the same thing. These 'seem' dry. I've also read that it could be the RABS. Is there any testing to determine if the RABS is definitely the problem other than by-passing it?
View 9 RepliesI just replaced the front break pads. I didn't replace the rotors or get them machined, didn't look like they needed them. Once I pushed on the brakes (truck off) I noticed that brake fluid spilled out the brake reservoir. I'm guessing it happened when I compressed the piston into the caliper? I took some of the fluid out of the reservoir and now its at MAX (I didn't bleed them). I've only been only be able to stop and go on the driveway (I'm waiting on a new radius arm bracket). The brakes seems spongy, the brake hits the floor. ABS and Brake lights came on then turned off once I started to pump them when I turned the truck 'on'. Do I just need to actually drive and "break" the breaks in?
View 2 RepliesBefore I get started... My truck is a 2006 F-250 Super Duty XLT 6-speed 4x4 with a Limited Slip.
I just got finished with a big job on my truck. New pads all the way around, turned rotors, new emergency brake shoes, hardware, and backing plate as well as replaced the rear wheel bearings both inner and outer as well as the axle o-ring and inner seal. Also, took off the rear pumpkin cover painted it and put fresh fluid in, went with Mobil 1 75W140 LS.
Took it for a drive and the brakes work great. Followed the directions for breaking in the emergency brake which worked fine.
Now the problem is I'm getting rattling from possibly all of the wheels. Definitely from the front driver and at least one of the rear wheels. It was so dark I didn't get a chance to look at it I just pulled it back in driveway.
I'll start looking at things tomorrow but, any common mistakes or things I should check first?
I have a '86 Fod Bronco that I have changed the brake lines on and the brakes will not stiffen up (they weren't that good before the switch either). The master cylinder leaks a couple thimble full after driving and it seems to pull a little while braking, but both the disc are shiny so the calipers are not locked. The pedal is still soft even if something is going on otherwise. I have tried bleeding having someone pump the brakes 5-10 times and hold it while I bled it and repeated 10 times on each bleeder screw using 32 oz of fluid, but apparently I did something wrong. All of this to say, have any of y'all used any brake bleeding vacuum kits and which ones would you recommend?
View 7 RepliesMy dad is having problems with his truck, brake pedal goes all the way to the floor even after bleeding all the brakes and the master cylinder. The wheel cylinder didn't have clips in it and he fixed it and it hasnt changed. What do we do? Its a 1993 f150 4.9l.....
View 4 RepliesI did a complete rebuild of my brake system in April. Drums, shoes, wheel cylinders, springs, hoses, pads, rotors, calipers, master cylinder, proportioner valve and flushed all the lines and refilled with synthetic fluid. I have made five trips from Southern California to Idaho hauling home furnishings, one trip to Oregon and one trip to Northern California since overhauling the brakes with everything working great. Now something strange is happening. The brake pedal goes to the floor with very little resistance. It isn't spongy like there is air in the lines. It just goes to the floor if you push it all the way down.
The truck stops ok but it is really scary with the pedal going down like that. You can feel when the rear brakes come on because there is a little resistance in the pedal when they come on. You can actually lock the rear brakes up and skid the rear tires. If you push the pedal down further the front brakes start coming on and if you push all the way to the floor the truck will nosedive and you will get planted in the windshield.
I wonder if the aftermarket Bronco Graveyard proportioner valve is blowing all the pressure to the rear wheels because it won't do it if you take the vacuum off of the vacuum booster. You have full pedal when the booster is deactivated and all the wheels operate normally with the exception of having to plant both feet on the pedal to stop it.
I was fueling up my 06 F-250 yesterday and smelled hot brakes. I checked and found the right rear was really hot. After it cooled down I was able to drive on home and it was not too hot when I got here. I was towing a trailer with my tractor on it so I had a pretty good load. It was over 6 miles to my house with stop and go traffic and no hang up. What should I do to keep this from happening again? I don't drive this truck much but when I need it, I need it to be dependable. It has 99k on the clock and is a gas job.
View 1 Replies 92 F250 4x4 with 140,000 mi. Abs light came on, Replaced the sensor on the rear axle, Light is still on. When the light comes on the brakes still work but it takes more pedal to stop. Now the Brake light comes on, It has new pads on the front, and its bleed out good. When you drive it some times it works fine, then out of the blue it lights up.
I have checked the fluid level, parking brake switch, and even swapped the abs black box with another, also bleed the bleeder on the left frame rail. When the lights come on you can pull off the road and turn off the motor and restart the lights stay off for several brake applies, then sometimes they light back up. The light issue is not that bad to me but it drives my wife crazy. I am more concerned about it taking more/harder pedal to stop.
1984 f150 with a new master cylinder, new brake booster, and new fluid. I did use dot 4 fluid (as opposed to dot 3) and bled out the system. This was about 9-10 months ago.
Just recently I noticed my brake pedal was going further down before I stopped; but I stopped. Since I switch between my car and truck a lot I thought this may have just been my imagination. What finally clued me in was when I couldn't stop as easily that something was obviously wrong.
Checked the master cylinder and the front reservoir was obviously empty. I couldn't find an obvious leak so took it to a shop. The added more fluid, bled the brakes and said its fine. They couldn't find a leak either.
Sooooo, any thoughts as to where my front brake fluid went? I'm assuming they took the wheels off and looked at the calipers too but I'm not sure I'll find out when I go pick it up in an hour. Could the dot 4 fluid have something to do with it? The brake lines, mast cyl, booster, proportioning valve and calipers are all bone dry. No obvious fluid leaks. Soooo now what.
Is there a good way to bend brake lines without a bender? I have two brake lines to bend that are probably no longer then 3 feet and don't want to buy a bender.
View 6 RepliesI am having trouble big time getting air out of my brake lines. I put new front pads and rotors on and also had to replace the brake line coming from the caliper as it kind of crumbled and needed to replace the next line up that goes to the ABS block on the left front. After doing this, I bled that wheel only and at first it was ok until the brake line on the right front at the caliper also broke when I was pushing on the brake pedal with the truck running, spewing fluid all over. I have tried to bleed using a decent vacuum bleed setup from Advanced Auto but keep getting massive amounts of air coming out and when I start the truck and hit the brake pedal, it goes to the floor. Could the master cylinder be bad? I have checked every connection that I made and all other connections and there are no leaks at all. I am stuck in the garage! The truck is a 1999 F150 4x4 with 4 wheel ABS.
