Every 2 to 3 days I have to add brake fluid and there is always a puddle under the rear driver wheel. Whats wrong and what do I need to repair it?
Why is my corolla leaking brake fluid from the driver rear wheel on 1999 Toyota Corolla
The rear wheel cylinder has a cup shaped seal inside it, the seal must have failed and it is necessary now to replace both rear wheel cylinders and the rear brake shoes if they have become contaminated.
Either your rear wheel cylinder or if you have disc brakes your caliper is leaking brake fluid or the connecting brake line has a leak, Need to have a shop repair this before it gets worse and your brakes fail.
