Help!! major brake problem....

bigal0043 · 09-30-2005, 01:43 PM

what i found weird was if it had a internal leak wouldnt it be draining out some of the brake fluid out of the resevoir? because mine is still topped off hasnt dropped any at all...

Well yeah, that was mentioned by someone earlier. The seals get soft and allows the fluid to blow by the seal on the piston inside the master cylinder. You can tell a lot of the times by just putting light pressure on the brake pedal and you can feel it go right to the floor. This doesn't always work, but many times that is one way to tell that it is an internal leak, or blow by. Usually you get some minor leakage into the brake booster.

Just go buy a brake master cylinder at Advanced auto or another parts store and put it on. Make sure you bleed the master cylinder first then the wheel cylinders. It wouldn't be a bad idea to make sure the fluid comes out clean on all the wheel cylinders so you have fresh fluid in the system.

Keep us informed.

Alright ill update everyone... there was an option for an wideband on my turbo elbow and it fell out... must not have been tight... but anyway that was blowing the exhaust air right on my brake lines causing it to boil my brake fluid... So my problem is fixed now...
