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.

I've got an o2 camry with 150K that seems to be losing brake fluid from the "right" side of the reservoir. Which brake lines are supplied by the "right" half of the master cylinder reservoir? I have read that they could be diagonally piped.

View 12 RepliesToyota - 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?

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.

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.

View 6 RepliesFord F-150 (2009-2014) :: Low Brake Fluid Dash Lamp Illuminated / Blown Master Cylinder Booster Assembly
Just wanted to report another F150 with the blown master cylinder problem and had a few questions regarding the issue. Its a 2014 Screw EcoBoost with about 12500 miles located in Michigan.
I was driving last Friday (6/19) when the low brake fluid dash lamp illuminated. I made it to my final destination, when I began to back into a parking spot the brake pedal dropped to a position about an inch off the floor. Parked the truck and popped the hood to find almost all of the fluid gone. Only having fluid in the rear axle reservoir of the brake circuit. Pulled the vacuum sensor and the booster is filled with fluid..
Called Ford, had it towed to the dealer and its been sitting there ever since.... They have no loaners and have not even looked at it yet. I'm going to assume no parts are in stock just like all of the other threads I have read on here about this issue.
A few questions I have for those of you who have had this problem or have knowledge about it.
1. How long did it take for your truck to be repaired?
2. When the master cylinder seal leaks all of the fluid into the booster and the booster is pulling engine vacuum; does this mean that brake fluid is then pulled into the crankcase of the engine?
Really looking to get my truck back soon cause I love driving it! But the '74 F250 will have to do for now ....
Camry :: Master Cylinder Leaks Caused Faint Squeaking From Brakes
I have a 2004 Camry LE with 214,000 miles on the clock, and this car has had needed maintenance pertaining to the braking system ever since I bought it in January. Let me give you some background on past issues/maintenance before I dive into my current issue.
During the test drive, the brake pedal felt extremely soft/spongy, having to travel a lot farther than any other car I've driven (even my father's full size pickup had stronger brakes). My dad dismissed it just being the way the car was. In hindsight I would've walked away or slept on it, but let's just say I was pressured into buying the car right away.
We took it to my trusted local mechanic a few days later for an overall inspection, and he said the front brakes/rotors needed to be replaced. He said the rear brakes were thin, but could be replaced later down the line. So we replaced the front ones, expecting it to have some improvement. In reality, the brake pedal force was still the same as before.
A few months later, after hearing faint squeaking coming from the rear brakes, the brake light started to illuminate intermittently. That's when we decided to replace the rear brakes/rotors. After we replaced the rear brakes, braking motion was dramatically improved, and I did not have to push the pedal very far to achieve adequate braking power. It was great,while it lasted.
It gradually started to go back to the way it was, which is really disappointing. After growing tired of the problems, I decided to check the brake fluid level in the reservoir, and it was practically at the minimum line! Figuring it was a brake line or master cylinder leak, we took it again to my mechanic to have him inspect the braking system. Much to everyone's surprise (including my mechanic), there were no leaks to be found and he told me to come back if it gets worse or the brake light comes on. HOWEVER, when I drove it home from the mechanic, the brakes felt the way they did when he put the rear rotors on. On the service record, it said he just looked for leaks and readjusted the rear rotors. This was about a month ago, or at 209,000 miles.
However, as before, the brakes slowly started to loose their "bite" again and sure enough, the master cylinder had lost fluid; albeit not as significant as before, but enough to require topping off. In addition, whenever I'm decelerating on the freeway (from let's say, 75-60 MPH), the wheel shakes as well. This wasn't really present before.
My patience is running thin with this car; we've easily spent half the value of the car on maintenance.
Camry :: 2002 LE Master Cylinder Reservoir Loose When Engine Not Running
Our 2002 LE Camry master-cylinder reservoir is loose, at least with the engine not running. Is this normal? It moves about 1/4", side-to-side. With the engine running, the pedal almost goes to the floor, but I've been told that's normal. I'm not sure that it is, but my wife seems to get by with it that way. Our engine is 4cyl.
View 4 RepliesSanta FE SM (2001-06) :: Whine Noise Only When Turning Right - Power Steering Reservoir Leaks Fluid
I have a 2004 Santa Fe 3.5L with 85K miles. TB, WP and all belts changed at 75K. Have had this whine noise when I turn right, very high pitch noise. On top of this there is now Power Steering fluid leaking from the reservoir and base and brackets are full of fluid... Needless to say I assume it is the reservoir seals giving up but why the noise only when I turn right? No noise when I turn left.
What could it be? Also where can I find parts online that are cheaper than the stealership? I called them and they quoted me $72.00 for this piece of plastic!!
What else should I change? There is also some "oil/fluid" coming down a pressure hose but I believe this is due to the oil dripping from the reservoir...
Any manuals I could use to view this? I bought the Haynes manual and it's worthless!

So I'm in the process of doing a rear brake job on a 2002 Pontiac Sunfire. Drum brakes. And (shocker - especially for a northern car that never had the job done before) the drum won't come off. I've spent two days with a propane blowtorch, PB Blaster, and a 3lb hammer. No dice. It won't even budge.
So now I'm thinking about taking an angle grinder to the drum and just replacing both (probably necessary, as I'm sure it's in terrible shape). I'm really at my last option here.
Brakes - Pontiac - Sunfire :: 1997 - Squealing Noise Coming From Brake Pedal
After 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.
Explorer :: Fluid Squishing Around Master Cylinder After Brakes Bleed
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.

View 1 RepliesSanta 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.
