What is the purpose of the rear brake caliper?
In simple terms, a brake caliper’s purpose is to squeeze the brake pads against the rotor to stop the car. There are two main types of calipers, a single piston and a dual piston. Most front calipers are dual piston but many cars use single piston calipers on the rear, where less braking force is needed.
How does the rear brake caliper work?
How It Works: Rear Disc Caliper with Parking Brake. If the parking brake uses the rear discbrake shoes instead of a separate set of drum brake shoes, there is a mechanism in the caliper piston cylinder to push the piston and apply the rear brakes when the driver operates the linkage . That mechanism, which is connected to the parking brake linkage, has a screw setup to compensate for the fact that in normal footbrake operation, the piston automatically moves out to adjust for brake
How often to rebuild brake calipers?
There is no hard and fast rule for caliper rebuilding frequency. Some calipers won’t need to be rebuilt during the life of the vehicle. High-powered race cars may need to have calipers rebuilt several times per season . At each pad change, inspect the calipers carefully.
How much does it cost to replace a brake caliper?
Calipers are the most difficult and expensive aspect of the braking system to replace. A single caliper can cost up to $130 . A complete brake repair – one that includes pad, rotor and caliper replacement – typically averages between $300 and $800 . Nov 19 2019
How do you rebuild a brake caliper?
Put a fresh dust shield on the piston. Using a compression tool, force the piston all the way back into the cylinder. Once you’ve managed that, replace the dust boot on the caliper, stretching it so it fits neatly in the groove. Now you’ve rebuilt your brake calipers and you can reassemble them.
What are the parts of a brake caliper?
A brake caliper forms a significant part of a car’s disc brake system. There is usually one per wheel (supercars can have two per wheel) and it houses caliper mounting bolts, bushings, pistons, seals, dust boots, retainers, noise shims, the brake pads and anti-rattle clips.
