How do i Change rear brakes on Lexus is300?

Answer 1

Very simple. After you have safely raised & supported the rear of your IS & removed the wheels, you will see a through-pin on the outer edge of the caliper. Remove the pins' retainer clip & pull the pin to the outside direction. This will free up the anti-rattle clip which is a single piece for both pads. Then simply pull the pads up & out of the caliper. There should be two anti-squeak shims behind each pad. Depending on the brand & quality of your replacement pads, you may need to clean & reuse those shims. I recommend you always purchase new shims & anti-rattle hardware. But if you're 'on the cheap' & they aren't broken, should be OK to clean & reuse. Use a small wire brush to clean out the area of the calipers where the pads sit in. You will also need to push both pistons back into their bores of the caliper to allow room for the new, thicker pads. A large flat screwdriver will accomplish this easily. It may be easier to loosen the master cylinder cap to allow to fluid to more quickly flow back into the cylinder.

Assembly is the opposite of what you've just done. Pretty simple really. No need to remove or unbolt the caliper on this design.
