So..... Yesterday my dash brake warning light came on like the E brake was engaged. Well I looked and fluid was kinda low. I jammed the brake pedal real hard this morning and sure enough it went off. Guess the proportioning valve was confused. Any who when I did that I checked for leaks and bam. My rear left brake drum had fluid pall over it coming from the brake line. I guess this mans the seals on the wheel cylinder are gone? How difficult it is to replace a wheel cylinder??
If this helps get a cheap $ 22.00 hand held vac pump from harbor freight. It makes bleeding the air out alot easier. Just follow instructions with the unit. Also use to diagnois vac leaks on a/c controls/problems, etc.
