A brake job goes easier when the tool saves your hands. This ratchet brake caliper tool uses a 360 degree ratchet you can work from any direction, which reduces hand fatigue, while two parallel spreading plates put even force on the caliper pistons. It works on double and four-piston fixed calipers and on single and two-piston floating calipers.

Swing the long lever handle to expand and retract the plates, and use the ratchet reversing switch for positive and negative regulation. Made of high-strength, corrosion resistant alloy steel, this brake piston tool and brake piston compressor is a disc brake caliper tool for all disc brake caliper press ratchet wheels, ideal for automotive brake pump adjustment and among brake tools that suit most large trucks and commercial vehicles. It compresses each caliper piston with control.
