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!!
