I have a 98 Toyota Corolla and was replacing the rear brake shoes and drums. I completed one side and without putting the drum on either side I pumped the brakes a few times. Yes, both wheel cylinders came out. I told my friend that I now have to replace both wheel cylinders. He says NO. He said when I pumped the brakes without the drums both thingies came out. What do you gusy think? Am I right or my friend? Prior to this, I inspected the rubbers on it and I saw no moisture at all! If my freind is right, do I have to bleed the system???? I cleaned both wheels with brake cleaner and they are spot free. Thanks!

If the cup seals are fine and the cylinder bore looks good, you can put it back together.Be careful not to cut the feathered edge of the seals.

All this mis information from them "mechaniks". six wrong answers. Got to be careful who's advice you take. Now that the rant is over. First thing, ANY time you do a brake job or remove the brake drum for any reason you must buy a kit. not a wheel cylinder, just the kit. No matter how careful you are you will disturb the seals in the cylinder and I guarantee you it will leak. Remove the old cups and use a piece of 380 grit emery cloth, pick up a sheet when get parts, And clean the inside of the cylinder until all old rubber is removed. Use a light to inspect closely. wipe clean and carefully assemble new parts. You will replace brake fluid in cylinders when you bleed them I hope you know how to back off the brake adjusters before you put the drums back on

No, you shouldn't have to replace them. Cleaning was OK, re-assemble them using brake fluid as a lube. Yes, you do have to bleed the system. Make sure the rubber cup are installed right,wide part of cup to the inside of cylinder.

This is what I would do. Loosen the lines to let the fluid out, then with your hand push the cylinder back in. If there is no leak like you said, then everything sould be fine just put the lines back and bleeds them.

if you can put the cups back in without tearing them(even a knick) then all you will need to do is bleed them. be patient....I have faith. it'll be ok.
