Brake Drum, Rear

Servicing brake drums requires the technician to recognize asbestos fiber dust risk because inhaling this dust creates health problems. Your work area should use a certified asbestos dust vacuum to clean brake and clutch assemblies in compliance with OSHA regulations while properly tagging and sealing the collection bag before disposal to dumpster services. A vacuum with appropriate asbestos fiber cleaning capabilities is essential for this task so technicians must wear government-approved toxic dust purifying respirators in its absence. Only brake and clutch repair technicians should be permitted entry into regions with asbestos dust while these areas must remain strict kept with warning boundary signs. The procedure starts by releasing the parking brake control fully before removing tension on the parking brake system through the front parking brake cable pull and conduit insertion and suitably pinning the retainer. First raise the vehicle and implement support. Remove the wheel assembly and tire together. To prevent brake drum distortion avoid the use of brake drum pullers and torches but if rust adheres the drum to the axle shaft flange tapping the drum center should free it. After the brake drum refuses to detach the technician should start by adjusting the brake adjuster screw before disconnecting the brake shoe adjusting lever while employing a brake adjustment tool to succeed. Brake drum replacement is mandatory when the inside diameter measurement from a brake drum micrometer exceeds its maximum limit. The installation of new brake drums requires complete removal of corrosion and dirt from wheel mounting surfaces next to brake drum surfaces to prevent wheel nut loosening which could lead to loss of control. To finalize installation work on the brake drum, start by fitting the tire and wheel assembly to the vehicle while lowering it onto the ground. Then unscrew the pin from the parking brake control device and test the parking brake functionality. After finishing with your checks you should drive the vehicle.
