Rear brake caliper tool

What rear brake caliper tool do I need to replace rear brake pads

Rear disk brake calipers with integral parking brake mechanism are quite different that the front calipers. You’ll need a rear brake caliper tool to retract the piston, because you can’t just push the piston back into the bore.

You have to screw the piston back in. To do that you need a rear brake caliper tool that fits into the slots in the face of the caliper piston, and the tool must match the manufacturer’s pattern.

Lisle 28600 Disc Brake Piston Tool to retract piston on rear brake calipers

Lisle 28600 Disc Brake Piston Tool is a square block with 6 different peg patterns to fit into face of rear caliper piston. Insert a 3/8″ drive extension and turn with ratchet to screw piston back into caliper bore

Some tool companies sell an inexpensive square block with

pegs on it and call it a rear brake caliper tool. The problem is you have to push the tool and turn at the same time. They barely because they keep popping out of the slots on the piston face.

This Lisle 25000 Rear disc brake caliper tool kit eliminates the pop out problem. You install the tool into the rear caliper (on or off the car), select the correct piston adapter and then screw in the piston. Since the screw pushes against the caliper fingers while it rotates, it keeps constant pressure on the piston while it screws back into the bore.

It’s a single operation with no slip out. It’s pricey but will save you a lot of time and you can use the curse words for another occasion.
