Caliper

To remove the brake caliper a person first has to take off the tire and the wheel, then disconnect the brake hose from the car brake caliper while making sure copper gaskets are not stuck on the caliper nor on the hose. Replace and remove the old copper gaskets by installing NEW copper gaskets. Use rubber plug (or equivalent) to seal the end of brake hose to reduce excessive break fluid loss and contamination. After that, remove the brake caliper slide pin bolts and pull brake caliper off the mounting bracket. For installation, mount the brake caliper assembly to the mounting bracket while installing the guide pin bolts and fixing with 40 Nm (29 ft. lbs). Remove the rubber plugs from the brake hose, then install new copper gaskets, and bolt on the brake hose, tightening the brake hose bolt into 40 Nm (29 ft. lbs.). Finally, bleed the system, replace the tirer and wheel, and bring the vehicle rammed.

The brake caliper repair requires starting by removing the tire and wheel. To replace the brake caliper properly detach the brake hose from the brake caliper but keep the copper gaskets free of both components. Dismantle all copper gaskets then install new ones in their place. The end of the brake hose requires a rubber plug or similar device to stop the loss of brake fluid while keeping the system clean. Brake caliper slide pin bolts must be removed before pulling out the brake caliper from its mounting bracket. When installing the brake caliper assembly fit it onto the mounting bracket while guiding in the guide pin bolts and torque them to 40 N.m (29 lb ft). After removing rubber brake hose plugs you should install new copper gaskets and bolt the brake hose back in place while tightening the bolt to 40 N.m (29 lb ft). After completing brake system bleeding the vehicle owner must reinstall the wheel and tire before lowering the vehicle.

Take off the tire and wheel before removing the brake hose from the brake caliper, seeing that the copper gaskets don't stick to either part. After that, take off the worn-out copper gaskets and put in brand new ones. Place a rubber plug or equivalent over the brake hose to keep brake fluid from leaking out and the system clean. Take out the brake caliper slide pin bolts first and then remove the brake caliper from the mounting bracket. To install, put the caliper assembly onto the mounting bracket and secure it with the guide pin bolts, tightened to 40 N.m (29 lb ft). Once the rubber plugs are off the brake hose, fit the new copper gaskets, put the brake hose onto the brake caliper, and secure it with the bolt tightened to 40 N.m (29 lb ft). Finally, do the brake bleed, put the wheel back on, and lower the vehicle.

Replace the pistons or caliper.
