While searching here for information on changing the brake fluid, I came across a thread that stated: You need a Lexus scan tool to bleed the brakes properly. I've bled brakes and other cars without having a scan tool. I've never bled the brakes on my 09 ES350.
View 4 RepliesI DIY most of my vehicle maintenance (oil, brakes, coolant, filters, etc.) so I figured the brake fluid wouldn't be an issue on the GX. However, while searching for the proper DIY procedure I found a number of posts that claim some Lexus models can ONLY be flushed at the dealer with Techstream.
Is this true for the GX or will the typical DIY work (pump brake and hold down, release bleeder valve to bleed fluid, close valve release brake petal and repeat)?
One thing i noticed on the GX is that the brake pedal will not presurize the lines if you pump it with the car off. That itself tells me I may be in for a surprise if I try the DIY method...
I have a 1999 Ford Explorer Sport 4.0 SOHC.
I change the rotor, calipers, and pads on the front end.
When I went to bleed the brakes I got some fluid, then I got none.
I can hear fluid squishing around up near the master cylinder, but none coming to the caliper.
I see a bleeder screw on the master cylinder.
Before the car came to me the person had, had low fluid, but had brakes. Now the pedal just goes all the way to the floor with no effort.
There are no leaks or broken lines anywhere.
My driver side caliper will not bleed fluid, is it safe to say that the caliper needs replacing.

On my 2011 Prius maintenance schedule, there is plenty of direction about inspecting brakes; however, there is no indication of when to flush and replace the brake fluid. My wife travels 60 miles/workday, but hits her brakes about 6 times/day. I would expect that normal braking would result in pad replacements more regularly than we are going to have. I did most of the 60K inspection, but took the car to a trusted, local mechanic for undercarriage inspection and a professional look-see. They indicated that the brake fluid should be replaced every 3 years, and I OK'd a flush and refill. Is there any professional guidance on the replacement interval? I know there are a lot of opinions, but I wonder if there is any published authority.
View 15 RepliesBack, I flushed when it turned opaque...
Then I bought a car engineered to last more than just a couple 100K miles and was surprised to find a lot of items in the preventive maintenance list that I never thought about.
It recommended flushing every 30K or 2 years. A bit of research showed this was also recommended by several other manufacturers. Even more common with advent of ABS.
So now I try to flush at least every 2 or 3 years.
I still have not found any recommendations from Ford or GM? Either I'm blind or (cynic stepping in) they still don't expect vehicles to last that long... Or like to sell replacement parts?
I'm not too familiar with these trucks, but I've been working on my buddies 1999 e350 ford van.
The other day we were going out kayaking, and the brakes locked up, we were able to drive it home, but it was obvious the brakes were holding the truck back. decided to check it out today, found one front and one rear caliper were sticking, the dual piston calipers only had one working, which I believed to be causing the pads to get pressed together crooked, and caused them to "lock up" or get stuck.
anyways, got the new calipers on and no more sticking, so I bled the brakes started in the front and went all the way to the back, did every caliper. brakes feel firm with the vehicle off, but instantly when the van is started, the pedal goes to the floor. it still stops okay, but the pedal feel is not nearly where it should be.
I got all of the air out of the system, but the abs light is on, and has been for a while. I'm wondering if there is something else that needs to be bled in the abs? someone was telling me about bleeding the abs motor?
What is the process for flushing the brake fluid for a 2007 or any other year from the Lexus Service Manual for our cars? I have read what I believe is the correct process on various threads but would prefer to read the service manual directly.
View 1 RepliesI have a 2012 LS 460. When the moonroof is closed the aft section is not flush with the roof. It's about 1/4 inch low. I don't think this is normal.
View 2 RepliesI am fixing up a Mrk IV Golf. One of problems I am having is that the brakes are not firm despite being bleed multiple times. The brakes work but the pedal does not inspire confidence, and I know there is braking performance being left on the table. The brakes are to large and the car is to small to brake as slow as it does. Are Golfs a cross bleed system? I have be bleeding them like I would on an old American car, which is what I normally work on.
View 2 RepliesI have a 2002 camry and I flushed my power steering fluid today using the following procedure:
- emptied the reservoir
- connected return hose to a bucket
- added new fluid (ATF dexron III - from toyota dealer)
- jacked front wheels
- turned steering wheel side to side till new fluid came out of return line (my reservoir did get empty couple times in the process so air may have went in)
- lowered the vehicle
- reconnected the return line to reservoir
- ran the engine and turned side to side couple times (did not see bubbling and fluid level did not drop)
I took the car for test drive and noticed that my steering wheel was still making noise when turning. Also, when i was turning the wheel side to side with hood open, I noticed a change in the sound. There was a sticking sensation and steam pressure release noise when I locked the wheel on either side.What could be the problem?
I have a 2002 Kia Rio Cinco, (named Simple Jack) with about 150k miles on it, that I have been bringing back from the dead. I've replaced the shocks and struts, brakes, wheel hubs, wheel bearings, part of the brake line, the timing belt, motor mounts, fan, valve cover gasket (needs to be redone because my mechanic got sloppy), spark plugs & wires, windshield and wipers, and the radio. I sound proofed the interior, pulled the seats and carpet out and power washed them. I am also doing some body work on it. Normally, I am pretty good at troubleshooting the problems, but not-so-much doing the actual repairs. I tend to panic, and get paralyzed by the fear that I will break my car worse than it is.
The first was about doing a transmission fluid flush. I got the filter and the transmission fluid and while my ex-mechanic was breaking my car the last time, I asked if he could do the flush. He said he would not do it because the transmission was too old and it would break the transmission if he did it. Since the fluid looked dirty and probably had not been changed for a while, his logic was that the parts had a layer of dirt on them that would be flushed away with the fluid change. This would interfere in the operation of the transmission because the parts would no longer be able to make contact with each other.
At the time, this made sense to me. However, after some less than stellar repair attempts, I have some doubts as to the validity of his claim. So I am asking you all if this makes sense.
The second question is a problem with rattling. I had purchased the tie rod ends, front stabilizer and bushings for the suspension. I asked my mechanic to change all the parts when he did the front shocks and again I asked when he did the front wheel hubs. He said that I didn't need the crap. So my car has a weird rattling when I drive. It sounds like it comes from the top of the engine, but at speeds around 60mph, I have some vibration in the steering, too. I am concerned that something may be wrong with the steering or maybe it's just the alignment. However, I think the rattling may be independent from the vibration. I have not been able to determine the cause of this and my plan was to just keep replacing parts until it is fixed. I figured I will have a new car by the time I am done. What I can check next? Should I do the tie rod ends? The bushings? The CV joints? I know I need a new mechanic.
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.
I took my 2010 F-150 for brake job and ended up with brake fluid in intake!! How that happened?
View 12 RepliesI have never noticed before but today I noticed the fluid inside the brake reservoir was bubbling or splashing around , whichever.What would cause this. I did just finish up on an intake manifold gasket replacement job. Drove for the first time today and that's when i noticed the 'bubbles'.

View 1 RepliesI started to feel the brakes get spongy. So I pulled the master cylinder forward and turned the 7mm about a half turn. Also noticed the brake fluid level low. I topped it off. Drove down a steep hill....red dash brake light comes on.....plow truck stopped at the base of hill with on coming car. Used emergency brake.
The down side is that I don't have a dry area to pump and check where the leak is. The up side is I have a 2nd car to drive (yaris).....the truck only has 45k miles on it. Where is that area that is prone to leakage on these trucks....... 2004 heritage 4.2 v6 with stick shift.... only 45k miles ....
Wife came home and said that her brake peddle went to the floor once. Truck is in the garage with a large leak of brake fluid on the ground. I ordered a new MC but not sure this is the issue. There is fluid on only the right side of the booster, all associated brake hoses and lines going into the ABS module. The module also has lots of brake fluid all over it. Looks like there has been a leak for a while. Only one flare nut coming from the MC was some what loose (I gave it about a quarter turn and it's tight now.
Booster has some rust on the front of it near the center of the MC bolt locations. Before I put this new MC on I want to be sure this is the issue. Do the ABS modules tend to leak OUT when they are failing? I see that's a common issue with the Hyundai but I don't see anything about fluid leaks externally.
The truck has about 180k miles on it. I was thinking of cleaning everything up the best I can adding some fluid and running it to see where the leak is coming from...
Is there a write up on how to change the brake fluid or is it the typical pump, hold, then open and close the valve on the caliper from farthest to closest? Also, is it ok to use dot4 super blue fluid and do we have a vendor that sells SS Brake lines?
View 11 RepliesThe leak appears to originate somewhere around the master cylinder but I cannot locate the exact spot.
I noticed the problem when I started the car and it began to generate white smoke in the drivers side. I also knew it was not oil or ATF because brake fluid smells different. I pulled the cover by the master cylinder (MC) and could see an area that was wet under the MC.
I may have a reservoir leak but I cannot pinpoint at this time. Photos will be provided later if I can take some that show the issue.. I do know they are expensive and I do know that Toyota and Lexus recalled several models for a leaky reservoir.
I have to keep topping my brake fluid up every 4 weeks, why I have to do this?
