My car has front disc, rear drum power brakes. I have the following situation in the rear: one wheel cylinder driver side with broken off bleeder valve and the left brake line rusted pretty bad. The brakes work fine, but I'd like to replace the wheel cylinder and the left axle line. I have the axle line nuts loose which took some time with liquid wrench. I didnt loosen them up enough that fluid comes out. Wheel cylinder nuts look a little scary but I will start with the liquid wrench on them next. after I buy a new wheel cylinder and line, I will try to replace the parts but my problem is that Ive never bled brakes before. Ive have searched and found some strange answers without clarity on how to do it, especially concerning the rear wheels. Is there anyone that has the time or know how to explain how to do this job to a novice? I could always go to a shop but I wouldnt learn anything about my car that way and also risk someone butchering it. I was also wondering if I take my left rear line off, would I have to bleed every wheel and the master cylinder?
