The models with fixed calipers and ceramic
Brake Discs require some caution because of the limited space between the wheel and the disc; placing a strip of cardboard between the wheel and the disc before having the lug nuts removed helps. In case the calipers are worn out to the extent that they need to be replaced, it is often best to replace them rather than overhaul them since one can get new and factory rebuilt sets on exchange. It is recommended that in any case, calipers should always be replaced in sets,-two at a time. There are two types of calipers: other types includes the sliding and the fixed types. The sliding caliper is screwed to a bracket which is in turn fixed on the knuckle and the fixed caliper is directly fixed on the knuckle. First, one should loosen the wheel lug nuts, then, use the jack to jack up the vehicle and place it on jackstands, and then take off the wheels. Remove the brake hose from the caliper by undoing the banjo fitting bolt and for sliding calipers you also need to unbolt the caliper mounting bolts, but holding the guide pin with another wrench. Types of fixed calipers require the removal of the brake line banjo bolt together with the caliper to knuckle bolts. Remove the sealing washers and open the brake hose for connection to avoid contact and loss of the fluid. If the caliper is being removed merely for another part to be accessed, then do not remove the hose; to clear the area for other use, then use wire and suspend the hose securely without applying any pressure on the brake hose. To uninstall first remove the seal and then the sealing washers, and on reversing to ensure that the mounting bolts are properly tightened to the required torque, and tightening the banjo fitting bolt to the appropriate tightness, use the new sealing washers. At last, the brake system should be bled, and the hoses and connections should be checked for signs of leaking, before testing the brakes gingerly and then putting the vehicle back to its regular use.
