How much should a brake caliper move?
Floating caliper movement is normal behavior. You can easily check if the caliper is secure. It is fixed to the brake carrier using two slide pin bolts, the torque setting is usually about 35Nm, and you’ll likely need to remove the pin bolt dust caps to check.

Why does my car shift when I press the brake pedal?
Car shifting fast after braking: When you have sticky brake calipers the car will shift to the left or right whenever you press the brake pedal. This is a sign you have problems with the caliper bolts, pistons, hose or slides. These should be checked immediately and replaced.
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.
What should I do if my brake caliper is stuck?
Check the rubber boots and remove, clean, and lubricate the guide pins again. They can be a pain to remove when they have been stuck for a while – so a torch is a must to warm them up when trying to remove them. If your sticking caliper problem comes from the vehicle’s rear, there is a big chance of a problem with the parking brake.
When to use handbrake or front brake caliper?
The handbrake prevents the car from rolling when the car is at a complete halt. In extreme circumstances, the driver can use the handbrake to stop the car when the brakes fail. The front brakes often play a greater role in bringing the car to a halt than the rear ones. This does not mean you should replace one and ignore the other.
What does sprag mean on rear brake caliper?
The calipers use a “one-way clutch” or “sprag” inside the caliper piston. When the parking brake is applied, the sprag will recognize when there is 0.030” or more clearance between the friction material and the surface contact area on the brake pad.
