leaking brake master cylinder temp fix??

89se-5 · 11-12-2008, 12:36 AM

so my brake master cylinder is leaking enough to where my brake pedal goes to the floor pretty quickly and i know i need to replace it but i simply cannot afford to buy a new one right now but i need to get around and i am wondering if anyone may know of a way i can get another week of two out of it till i can afford a new one. or maybe someone has an extra one for a 1989 b2600i se-5 they can sell? anything would help and if not well thanks for taking the time to read this at least.

Don't put a stop leak in it your whole brake system will get messed up quick it will swell all the rubber o-rings up and you will have it replace or rebuilt it all ask my son he put power steering fluid in his RX-7 with stop leak I thought he knew better. He learned a good lesson. Bite the bullet till you buy a new one or go to a junk yard don't drive it we wouldn't want you to get hurt or hurt someone.

Where is the leak? The fluid has to be going somewhere.
In some race situations if the leak is located, the individual wheel can be isolated. The same is true for the either, the entire front or rear brake components.
Braking is not great, but it is better than none.
Is your master leaking into the booster?
If yes, failure to repair this right away will compromise the bosster, and this will add to the expense.
Sell some plasma or something. Brakes are pretty important.
Get that thiing fixed.
