Replacement brake discs and pads

Model: BMW Serie 3 E36 - Years 1990-2001
Part: Brake discs

Once the car has been raised on a lift or on a crik, remove the wheel on which the repair must be carried out. At this point, with the 6mm hex wrench, loosen the bolt fixing the disc to the hub. Using the screwdriver, release the retaining spring on the brake caliper. Identify and remove the rubber caps on the rear of the brake caliper fixing pins and, with the 7mm hex wrench, unscrew these pins. With the help of the fixed screwdriver, pry between the brake disc and the caliper so as to make the piston retract and create the right clearance to allow you to easily extract the caliper. Using the 16mm ball wrench, unscrew the fixing pins of the brake caliper support. At this point remove the old brake disc from the hub (in the event that it is stuck, give the disc a few blows on the front and not sideways to free it). It is advisable to brush and clean the hub of any rust residues and to apply grease to protect it from oxidation. Then apply the new disc (after having cleaned it with solvent from any residual passivating oil) aligning the passage hole of the fixing pin with the threaded hole on the hub: screw and tighten this pin correctly with the 6mm hex wrench. Refit the brake caliper support bracket. Apply a new set of pads to the brake caliper and refit the caliper. Finally hook the retaining spring back onto the calliper. Before starting again, it is advisable to pump the brake pedal until it opposes the right resistance to make sure that the brake caliper piston reaches the end of its travel and to pay attention to the first braking. The tools needed to perform this repair are: a hammer, a medium-sized fixed screwdriver, a 6mm and a 7mm hex wrench, a 16mm and a 17mm ball wrench.
