A: Service of the brake drum starts by lifting the entire vehicle while supporting it and continuing with the removal of lug nuts that secure the wheel and tire assembly. The next step after brake drum removal is to remove the brake assembly through unscrewing of screws while also removing the drum. Fitted braking drums must first be correctly positioned before installing screws to secure them. Insert the wheel with assembled tire onto the vehicle before installing its lug nuts then lower the vehicle down prior to tightening all lug nuts for a secure fit.
Q: How to service and repair the brake drum on Ford Focus?
A: Begin brake drum service operations by removing wheels along with tires but keep the dust cap aside for disposal. Using power tools on wheel hub nuts will result in spindle damage therefore it is essential to avoid their usage when removing this component. Installation of a brand-new bearing is necessary if the bearing inner races split away from the bearing assembly because disassembling a bearing will result in failure upon reassembly. The wheel hub nut should be discarded before moving forward with brake drum removal. The installation process begins with proper placement of brake drum together with wheel hub followed by new wheel hub nut application. The brake drum should be turned counterclockwise when torquing the wheel hub nut to 235 Nm (173 lb-ft) to protect the wheel bearing from damage. Cut off any potential sensor failure by maintaining a clean wheel speed sensor ring and keeping it away from magnetic elements. A fresh wheel hub nut needs installation because it provides proper clamp force which protects the wheel bearings from failure. Replacement of a new dust cap should follow before reinstalling the wheel and tire.
Q: How should asbestos fiber dust be handled when servicing the brake drum on Ford Ranger?
A: All repair operations on brake drums need special attention to asbestos fiber dust since inhaling this substance leads to health threats. Use a specific vacuum cleaner for asbestos fibers which can be either a Brake/Clutch/Service Vacuum or its equivalent to clean brake and clutch assemblies following OSHA procedures by labeling the bag properly then sealing it before notifying the trash hauler about the asbestos contents. Technicians must use government-approved toxic dust purifying respirators when dust generation becomes possible unless vacuum cleaning is feasible. The area producing asbestos dust needs to be confined with warning labels so only brake and clutch repair specialists can access that zone. A vehicle is unstable during braking so technicians must install fresh brake shoes and lining across both rear axle ends when the parking brake control is free from tension. The first step involves taking off the wheel combined with tire unit. Completely avoid the use of both brake drum pullers and torches to prevent any brake drum distortions. To remove a rusted brake drum that resists separation from the axle shaft pilot diameter technicians should use tapping between wheel studs at the center of the drum. Start by discarding the spring nut before pulling out the brake drum from the axle shaft. Users should apply the Brake Adjustment Tool on the screw nut while using a screwdriver to move the brake shoe adjusting lever off the brake adjuster screw. The users should then loosen the screw nut. A Brake Drum Micrometer should measure the inside diameter of the drum followed by new drum purchase when the maximum reading exceeds the specification on the drum. The termination of the installation requires performing the removal process in reverse order.
