Lexus GX 2004-09 :: Brake Master Cylinder Keep Compressing For About 4-6 Seconds Even While Driving

I recently bought a 2004 GX 470 with 89k miles. My dad did the 90k service like a champ and it runs very smoothly. However, I have recently noticed what I believe to be the brake master cylinder, which on a regular basis, has to keep compressing for about 4-6 seconds even while driving. We filled the fluid and it seemed to stop as I was pumping the brakes to test. But the next day it started again and the fluid is still at MAX level.

Ford F-150 - 1997-2003 :: Brake Bleeding After Putting In A New Master Cylinder?

...Is there anything special that needs to be done for brake bleeding after putting in a new master cylinder? I decided today to flush my system with my vacuum bleeder and now my pedal slowly falls to the floor at a light...No problems in a panic stop or otherwise, just falls to the floor slowly when braking...no leaks, so I'm assuming a master cylinder is an order....

Lexus GS 2013+ :: Brake Warning Light - Fluid Level In Master Cylinder At Minimum Line

Yesterday the brake warning light came on in my 13 350. I checked, and the fluid level in the master cylinder was at the "min" line. I don't think I've ever had to had brake fluid in any car before. Seems to be Ok today, but I was wondering if other folks have had this happen? Of course if it happens again I'll have to check the brake system. Just wanted to check.

Elantra XD (2001-06) :: 2003 - Brake Fluid Leak Coming From A Part Near Master Cylinder

I recently noticed that my brake fluid was leaking in my 2003 Hyundai Elantra and upon further inspection I found the leak was coming from a part near the master cylinder. I looked online and couldn't figure out if this part was part of the master cylinder or brake line or a part all on its own. I tried tightening it but It still leaks some. I read a similar post online and that it could just be that the washer needs replaced but I just wanted to check on here to see what the part is called and if I should just replace the whole thing. I included photos as well.

Ford F-150 (2004-2008) :: 2006 - Brake Light On Intermittently - Master Cylinder?

My son's 2006 F-150 4x4, with 107,000 miles, has in intermittent brake light on. I replaced the rear pads, as they were nearly into the rotors. The brake pedal feels fine in all braking conditions. Could the master cylinder still be going bad? Anything else to check?

Lexus GX 2004-09 :: When Brake GX470 Seems To Skip Until Come To A Complete Stop

I just recently got 2008 gx470 as a college graduation present in May. Very exciting having a GX as my first "real" car!!

After driving a few months, I have noticed that my brakes are acting a little funny. Whenever I brake, the car seems to "skip" until I come to a complete stop. It's not a very serious problem, but more of an annoyance.

I took it to the dealership and they told me that my rotors are "warped" and need to be shaved down. They quoted me for 600-700 dollars for the fix...

I just hit 43k miles

Santa FE SM (2001-06) :: Faulty Brake Master Cylinder?

I had this sad puppy noise coming from my brakes so I have now replaced my brake booster. When doing so I took my old brake master cylinder and put it on my new brake booster. When trying to bench bleed it it only came fluid from the P marked circuit. It came no fluid from "S". I guess it stands for primary and secondary.

I thought it was because I couldn't press the piston hard enough so I installed it in the car so I could use the brake pedal to get more power. But still no fluid from "S". Is the brake master cylinder faulty? The rear discs are unevenly worn.

Prius (2010-12) :: Noise From Brake Master Cylinder / ABS Unit?

I have leased my 2012 prius since April 2012 and about a year ago I began to notice the following noise originating from the master cylinder/ABS unit. The noise happens if I push the pedal firmly to the floor and occasionally during regular braking. The braking system seems to be working fine and regen braking is functional. I am wondering if this noise is a sign of an imminent failure.

Listen to audio recording....

Ford :: Brake Fluid Leaks From Top Of Master Cylinder Reservoir

Early 70's Ford truck. The brake MC fluid is filled but not overfilled, and doesn't leak at all when the truck is parked. It can sit there for a month and never leak a drop, parked. But when I drive the truck, even just around the block, then park, and look inside the engine compartment immediately the brake MC is dripping brake fluid. It appears the leaking mode is by the fluid somehow jumping up and coming over the top edge of the MC when the truck is in motion or when the brakes are applied. All my diy'er years of replacing brake master cylinders on Ford Galaxies, VW Rabbits, Corollas, and this truck, I've never seen this kind of weird brake problem before. On this MC design it seems there's sort of a rubber baffle inside the lid of the MC, and that's present and accounted for.

Toyota - 4Runner :: Master Cylinder Leaking Brake Fluid

My 2003 Toyota 4 Runner with 104K miles recently started showing a brake light off and on. The brake fluid reservoir was at the minimum level and there was some residue leaking from the bottom near a silver disc. Took it to a mechanic and was told it was most likely the master cylinder leaking brake fluid. Is this normal wear and tear or is it unusual in this vintage vehicle? I do not notice any brake slippage at this point. Should I take this to the dealer and ask why this master cylinder is faulty? I thought Toyotas were long life vehicles?
