Which way do you turn a brake piston?
Clockwise is the correct direction to turn the rear calipers as 2001GTTT said. Make sure you are using the rear caliper tool properly but it can take a lot of torque to get them to turn in. Also, make sure that you line up the cutouts in the piston so that they are vertical.
Where do the brake pad clips go?
The clips fit between the pads and rotor and push the pads away from the rotor. At the back of the caliper, you’ll find two complex-shaped little twisty spring clips. These springs hold the retaining pins in, which in turn hold the brake pads in.
How do you tighten a disc brake piston?
Place the wedge plate up against the outer caliper housing and tighten the tool until the drive arbor and wedge plate are working together to compress the piston. Continue to slowly tighten the tool by hand until the caliper piston is fully retracted into the bore. Loosen the tool and then remove it.
Where are the grooves on a disc brake piston?
Match up the correct adapter of the disc brake piston tool or the disc brake piston tool set to the screw-in type caliper. These pistons have visible grooves on the face of the piston. Many makes and models of cars employ different-size grooves that require different adapters.
How does hydraulic piston work on disc brakes?
A hydraulic piston extends from the caliper bore when demand is placed on the brakes. The movement of the piston squeezes the friction material of the brake pads against the metal surface of the rotor. When replacing brakes, the pistons must be retracted to make room for the thicker pads and/or rotors.
Can a rear caliper be turned clockwise to retract the piston?
Rear calipers can sometimes require the piston to be turned clockwise (or counterclockwise in some cases) to retract the piston. Knowing which type of caliper you intend to use the disc brake piston tool on will help prevent damage to the caliper or tool.
