J.C. Whitney Brake Caliper Single Piston

The J.C. Whitney single piston brake caliper is an OEM-style replacement disc brake caliper. It restores braking performance when an original caliper sticks, leaks or wears out. In a single piston design, hydraulic pressure pushes one piston to press the brake pad against the rotor. The caliper body slides on guide pins, so clamping force is spread across both sides of the rotor. This family covers front and rear, left and right positions.

Key Features:

• Single piston floating caliper design, made as a direct replacement for the original part
• Rigid caliper body, typically cast iron, for durability under repeated braking heat and load
• Seals designed to resist fluid loss and a piston built to retract smoothly after the pedal is released
• Protective coatings to resist rust and corrosion
• Machined inlet and bleeder ports for a leak-free hydraulic connection and easy bleeding
• Separate left and right versions for the front and rear axles, so the caliper matches the original mounting and brake line orientation

A worn or seized caliper can cause pulling, uneven pad wear, noise or a soft pedal. Replacing it helps restore even braking and consistent pedal feel. Replace calipers as a pair across an axle for balanced braking, and bleed the brake system after installation.
