Once the wheel and brake drum are removed, visually inspect the brake shoe lining (worn through) and replace the brake shoe set when the brake shoe lining is visible to be above the rivet head 1/32 inch(0.8mm) or the metal webbing of the shoes is worn out and complies with local inspection regulations. In 2-wheel drive pickups, jack up the rear end on jackstands, dismantle the drums, refracting and hold down springs, guide pins, parking brake connection, adjusting pawl, and spring, and remove the shoes with reference to the longer lining shoe location. Check that the shoes have no cracks, no heat checking or contamination, at least a 1.00mm (0.039 in.) minimum thickness of linings and also replace both sides where required. Clean the support plate and wipe the thread of the starwheel with grease and the pads of the brakeshoes. Installation requires one to take the parking brake lever and reversal of the dismantling operations and then to adjust the parking brake and the brake shoes by reversing the dismantling process again and by testing the brake pedal to ensure that it does not have sponginess. In the case of 4-wheel drive pickups and MPVs, the removal and installation procedures are the same as long as to check and clean the parts, lubricate where necessary, and to set the brakes. To the Navajos, lift and hold the car, take off the wheel and brakes drum, pull off the adjusting lever, and take off the springs and shoes, and observe the location of hold-down springs. Wipe the backing plate, lithium grease high temperature, and fix the new parts making sure that all the shoes are correctly placed and adjusted. Turn the brakes with a gauge or fingers and test that the rotation of the drum is free of drag. Drum brakes are self adjust but have to be adjusted manually after changing the shoe whereas disc brakes cannot be adjusted. When adjusting rear drum brakes, raise the car, take out the rubber plug, use the adjusting screw to increase the expansion of the shoes until they drag then take out the starwheel so that they can have freedom of movement. Do the same to the other side, making sure that there is equal adjustment to avoid pull to the brake, and the road test is only done when the brakes are safe and working.
