I have a 1993 Olds Cutlass Ciera with the V6 3.3 litre motor. I am leaking brake fluid somewhere and don''t know where. I have to add more fluid every week. Can anyone give me any info on where the fluid leaks from. I have tried parking on a dry spot and putting cardboard underneath but both are still dry when I come out the next morning. Any help would be greatly appreciated.

 

The lines from the brake reservoir to the brake cylinders are not pressurized when the car is parked, so fluid may not leak out then (good idea parking on cardboard though).


I would start the car when parked over a dry spot, and hold the brakes for a few minutes. That will pressurize all the lines, and hopefully enough will leak out for you to find it.


Check the lines to the front wheels, they flex all the time, and tend to crack when they get old.

 

Thanks Iflylow. I will do that in the morning. I am hoping that is all it is because i do not want to have to replace the master cylinder.
