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 14 RepliesEarly 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.
View 17 RepliesI'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.
View 8 Repliesput new master cylinder and bled brakes in 1978 jeep cj5 and now fluid is being forced out the rear brake reservoir in the master cylinder, if lid is off there is about a 1inch fountain of fluid that shoots up.

View 12 RepliesOur 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 RepliesMy 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?
View 2 RepliesI 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.
View 7 RepliesYesterday 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 RepliesI have power steering fluid leaking out of the bottom of the Brake master cylinder out of a round hole. Every time I pushed brakes it leaks a good amount of power steering fluid out. Why it would do this and is there a screw missing out of the hole or what?
View 6 RepliesJust 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 ....
my 2000 f550 master cylinder reservoir plastic is cracked from vibration and it would be good to know if it can be replaced separately than having to purchase a new complete unit.
View 2 RepliesSo my civic has been running hot this week. Had plenty of antifreeze. Oil.changes and tuneup are up to date. Started running hot monday so I went ahead and changed the radiator cap and replaced the thermostat. Still running hot at this point and im losing all my fluid from the coolant reservoir. I run my heat as a guide to when I lose all fluid. Once the heat turns cold I pullover and refill it up. Oil isnt milky and no white smoke. Could it still be a bad head gasket? Possible water pump? Plan to flush the radiator tomorrow.
View 4 Replies2002 camry: my boyfriend just told me he accidentally added power steering fluid to the brake reservoir a couple monthes ago....while i floored it on highway, i only reached 40, when let off gas, car came to a quick stop. later i jacked up rear and was able to turn back tires to rule out e-brake being stuck,when car is in nuetral and pushed (forward or backward) it comes to a stop whithin a foot or so ( it seemed like the brakes were being depressed) possible transmission or brake issue?
View 2 RepliesI am having a problem with my 2004 Toyota Camry XLE V6 brakes. For the past couple months I keep seeing the brake dash light turn on and the brake fluid is constantly going down but I don't see any wet spots under the car. I needed rear pads so I kept thinking that it was just the fluid going down because of worn rear pads but I changed the rear brakes last weekend and still have this problem. Today when I went to drive the car for the first time of the day I heard this loud noise every time I stepped on the brake pedal. I checked the brake fluid level and it was a little below low so I filled it back up. I kind of feel like I've had to fully press down on the brake pedal lately to stop the car. There's plenty of brake power but I feel like I have to push all the way down and I don't remember it being like that.

I have a 2010 F150 4.6 3V... The power steering reservoir is constantly losing fluid. I've purchased the truck,used, a few months ago, bought a warranty. The dealership has had it multiple times now and can't find the leak. They just keep replacing hoses and the problem keeps occurring. Also worth noting, the truck has 6" lift with 35s. I've have also pulled the radiator cap and found a decent amount of what looks to be sludge/oil inside. Dealership says it's probably just bad coolant.
View 1 RepliesI 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.
Which line goes to front brakes and which to rear from the master cylinder?
View 1 RepliesI 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.
I replaced my MC cap and gasket less than a year ago with a Dorman replacement and I'm leaking again, already. I don't want this to be an annual thing! Any good quality replacement? Is there any tip or trick to get the gasket to seal better?
