95 blazer 4.3 vortec engine. noticed that break fluid was leaking out of the inner part of the rear passenger tire. took tire and drum off and it looks to be leaking from a resrvoir behind the springs.
question: is this an easy fix. do i just pry the springs off, run to the auto zone and buy a new reservoir? or do i have a more serious problem?

Thanks for any help. gotta take care of this soon. i need to get to the firehouse tomm.

 

That reservoir is actually called a wheel cylinder and is what drives your rear brake shoes.
They are not generally difficult to replace as long as you can get the brake line removed without breaking it.

You will need to remove the brake shoes and all of the springs first. Then you will need to remove the brake line from the back of the unit. There should be 2 bolts that hold the unit in place. Once those are removed the wheel cylinder should come out rather easily.

Once you put the new unit in you must remember to bleed out the new cylinder to remove any air from the lines. Also be sure to use a good brake cleaner to remove the excess brake fluid that is likely to be just about everywhere. If your brake shoes are soaked in fluid then it is best to replace them. (remember to replace them on both sides of the vehicle)

 

appreciate the help, going to attempt it now

 

ended up just taking it to the mechanic and paying the $50 for the repair. Didn't have the time to try and fix it. Plus, it is just way to hot down here to sit out in the heat and attempt a fix.

 

So your mechanic replaced the wheel cylinder and all is well? Thanks for the follow up!
