How does the rear brake caliper adjustment work?

Rear Brake Caliper Adjustment. To adjust initially, the piston is adjusted outward by turning the nut on the lever or by cranking the lever. This ratchets the caliper piston outward just like using the emergency brake would do. This moves the piston outward taking up that distance between the rotor and the pads.

Where is the adjuster on a drum brake?

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

Can the parking brake be adjusted?

Yes, some cars have self-adjusting parking brakes, but in others, the parking brake might need to be adjusted if the cables are stretched, but otherwise in good shape.
