How do you remove the rear brake cylinder (hub) from a 1988 Chevy Blazer?

Answer 1

If it's the type I think it is ( no bolts )
They are a real bastard.
When you look at the backside of the backing plate, you will see what looks like a large spring clip holding the cylinder to the plate.
This clip needs to be cut off of the old cylinder. ( the new cylinder will come with a replacement clip )
However because of it's location and the fact that it's hardened can make this a chore without a flame wrench.
A Carbide cutter in a Dremal tool will do it.
The new clip can be installed with a large socket and a C-Clamp.
When you are done look at the heavens and curse G.M. for coming up with this method of saving 50 cents on bolts.

Answer 2

Lets assume you've already jacked the car up and have pulled both the wheel and the brake drum. The brake cylinder is usually mounted to the back plate attached to the axle. So you have to look behind the plate for the screw (usually 1, but maybe 2) that holds it in place. And you'll also have to remove the brake line that runs to the cylinder.

Answer 3

first you need lift you car on te rear axel and put a block on and remove the wheel if drum is stuck dont pry hard get a propane torch and heat arrownd the stud bolts them pry or pull ,dont removed the brake shoes only the top springs be carefull to dont let go the spring and losse you brake line before you losse the bolts on back if bolts frozze up use the torch ,dont worried you dont catch any fire ,good look

Answer 4

I agree with the previous answer. I think these cylinders have a steel clip that holds them to the backing plate. It would be best to have someone who has done them before do it. Hope you're not in too deep already.
