How do you repair a Lexus SUV RX 300 rear brakes?

I assume that you are wanting to know how to change the rear brake pads. First, loosen, but do not remove, the lug nuts on the rear wheels. Second, put the rear end up on jacks so that the rear wheels are off the ground. Then remove the rear wheels. Then you are going to see the caliper. On the back of the caliper there is one bolt and a pin attaching the caliper to the main brake assembly. You can tell these from the other bolts because there is a rubber boot around them. Now, you are going to remove the bolt which is on the lower part of the caliper. Once that is removed, the whole caliper will pivot upwards exposing the brake pads (you may have to giggle it a little bit to break it free). The brake pads simply slide out and can be replaced with the new pads. You may have to pry the piston which is part of the caliper back in because you are inserting new brakes. A screwdriver or clamp is handy to help you do this. Now simply repeat these steps in reverse order and you have yourself a new set of brake pads. Good Luck!!

I assume that you are wanting to know how to change the rear brake pads. First, loosen but do not remove the lug nuts on the rear wheels. Second, you are going to need to put the rear end of the car on jacks and then remove the rear wheels. You are now going to be able to see the brake assembly. Locate the caliper (the piece that looks like it is clamped onto the rotor). The top of the caliper is held on by a pin and a bolt. You can tell these from other bolts because there is a rubber accordion-like boot surrounding them. Remove the bolt with the boot (on the lower part of the top of the caliper). Then giggle the top of the caliper and it should pivot upwards exposing the brake pads. The brake pads are held on by clamps so simply wiggle the pads to remove them. You can now insert your new pads in the same way that the old pads were situated. Next you are going to need to push the piston of the caliper back in so that there is room for your new pads. A screwdriver or clamp can help you achieve this. Now all you need to do is pivot the caliper back down, bolt it on, do the same to the other side, put on the wheels, lower the car, and you have yourself a new set of rear brakes. FYI, when you start the car, pump your brakes a few times so that the pistons are compressed once again against the brake pads. Good Luck!!
