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


Apr 19, 2014

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 6.0L Power Stroke Diesel :: How To Get Master Cylinder Pushrod Out Of Hydroboost Unit

Im replacing hydroboost and master cylinder and I cannot for the life of me get the master cylinder pushrod (which must be reused) out of the hydroboost unit. There is a spring, retainer and pushrod that I cannot get to release. I know it has to be very simple, I just cannot see how it releases.

Ford Excursion :: Master Cylinder Leaking And Winding Up Under Hydroboost Unit Via Gravity

I replaced my hydroboost unit about 10,000 miles ago. Today I noticed it was wet under the unit. Only this time, it's not red PS fluid, rather, it is brake fluid. So, I assume the master cylinder is leaking and winding up under the hydroboost unit via gravity. Or at least that's my theory.

Any way Rockauto lists 2 motorcraft master cylinders.

One is BRMC-26 for Hydroboost
The other is BRMC-27 for speed control.

I have obviously Hydroboost, but also have speed control.

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.

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?

Camry :: Master Cylinder Reservoir - Losing Brake Fluid From Right Side

Lexus GX 2004-09 :: 2003 GX470 Brake Master Cylinder Leakage

Just purchased a 2003 GX470 with 160k and after the low brake fluid light came on I noticed the master cylinder had a leak. After removing the cover it appears the fluid has leaked for quite some time as the paint has started pealing from the frame. The brakes however appear to be working correctly. Upon purchase the front calipers were seized and I replaced both front calipers.

After having someone depress the brake pedal while I watched, the fluid leaks from the end of the master cylinder each time pedal is pressed in.

After doing some research it appears there is a rebuild kit for the master cylinder.

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.

Sonata NF (2006-10) :: Red Parking Brake Light Come On - Master Cylinder Level Was Low

So my May 2007 V6 Sonata with 143,000 km (89k miles) had the red parking brake light come on. Master cylinder level was low and there was evidence of something leaking on the driveway. Below the very back of the driver seat.

At the dealership they say I've got a leak in my brake lines. Say that the fuel lines should be replaced too since they are in the same compartment. So if one goes the other may not be far behind.

I was out of town and the car couldn't be driven safely so I was pretty much stuck there.When the dealership did the work a rusted bolt snapped near the fuel tank and they said that added an additional hour of labour to the work. In the end I wasn't charged for it. Tech said he had never seen a Sonata have the brake lines rust out like that. I got the brake and fuel lines done cause I plan on owning it for 6+ years.

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....

Ford Brakes/Suspension :: Why Are The Brake Lines Coiled Near Master Cylinder

Why the brake lines have 2 or 3 coils in them near the master cylinder? Makes it a real pain to work on anything down in that area. Always snags ratchets and stuff...

My brother and I were discussing it the other nite, and the conclusion we came up with was, the first guy ever who was installing a brake system had tubing that was a couple feet too long, and couldn't find a tubing cutter, so he coiled them up.

Then the next guy saw that and figured "hmm, so THAT'S how it's done", and so on... Kinda like the story about the lady who always cut off both ends of her ham before she put it in the broiler..

Honda - Accord :: 2002 - Old / Weak Brake System - Replacing Master Cylinder?

I have a 2002 Accord with about 130k miles on it and the brakes don't have nearly the power that they used to. The pads and rotors are due for replacement but even then, the system is pretty weak. Would replacing the master cylinder? What about simply replacing the brake fluid (I doubt it has ever been changed)? And/or the calipers? The car is in great condition and I really like it so I don't mind investing some time and money to get more years out of it.

Pontiac - Sunfire :: Brake Fluid Leaks Out Where Reservoir Attaches To Master Cylinder

I'm getting ready to work on a 2000 Pontiac Sunfire for a co-worker. They told me that brake fluid leaks out where the fluid reservoir attaches to the master cylinder. Could that be a bad master cylinder or something with the brake booster? It looks like there is a lot of sludge in the reservoir.
