how do you change wheel cylinder

Jack up the car, put jackstands underneath the remove the tire/wheel from the car, pull off the brake drum and look at the brake shoes and hardware, if anything at all looks wet or greasy or oily then you either have a leaky wheel cylinder or a bad grease seal. If the inside of the tire is oily then it's probably a wheel cylinder. An easy change for a mechanic that has brake tools but not for someone who doesn't have the specific tools for the job. By the time you buy all the brake tools that you would need, you might as well have a mechanic do it for you. Any backyard mechanic should be able to do a quick brake job in his sleep as long as he's got the correct tools and equipment. The brake shoes will have to be changed once they get brake fluid on them, they will never be able to be cleaned good enough as the brake shoe lining soaks up the fluid like a sponge plus the shoes for that car shouldn't be more than $20.00 for both sides. You might as well change the springs and clips as the hardware kit is about $4.00 more. Just make sure you get both sides done even if the other side is clean and dry, you should ALWAYS change brakes or any brake hardware in pairs and they come in pairs anyway. Kenny..
