There is a 14 mm bolt on back of caliper. Remove this & use a 4 mm Allen wrench to back piston into caliper.
You need to turn the piston clockwise and it will slowly retract as you turn.
Use a "C" clamp to fully retract piston into caliper body
Clockwise to retract piston into caliper body
Rotor "Out of Round" when rotating "High" spot will cause piston to retract into caliper body
Rotor "Out of Round" when rotating "High" spot will cause piston to retract into caliper body
Use a "C" Clamp to fully retract the piston into the caliper body
caliper piston does not retract with moderate C-clamp pressure - not willing to force it
a special scanner called a v.a.g. has to be used to retract the electronic e brake system, and will also retract caliper piston..DO NOT TRY WITH OUT TOOL !!!!!
You cant, it needs a 'C' clamp.
If it is the front brake use a "C" clamp to retract piston If it is the rear and the parking brake is used by this caliper piston is threaded and a special tool (not expensive) available at Sears or auto parts to "screw" piston into caliper body
After changing pads? - pump brake pedal to set pads against rotor To retract to change pads? If parking brake is not connected to this caliper - compress piston into caliper body with a "C" clamp - if parking brake is installed on this unit a special tool (not expensive) is required because piston is threaded Tool is available at Sears or auto parts ========================= If you're talking about the rear disk pads, they are adjusted using a small screw (hidden behind a nother screw) on the caliper which adjusts the parking brake. You need to turn this screw to back off the calipers in order to install the new pads. Since the calipers are threaded, no amount of pushing will retract them.
Remove caliper mounting bolts Slide caliper off rotor Use a "C" clamp to fully retract piston into caliper body If parking brake is used on this caliper piston is threaded and a special tool (not expensive) is required to thread piston into caliper body
