Final answer:
The correct method to repair a wheel seal leak that has glazed the brake shoe linings is to b) replace the wheel seal and brake shoes on both sides of the axle to ensure even and safe braking performance.
Step-by-step explanation:
When dealing with a wheel seal leak that has glazed the brake shoe linings, it's important to recognize that merely replacing the wheel seal will not address the contamination of the brake shoes.
The glazing indicates that brake fluid or grease has likely compromised the friction material on the brake shoes. This can result in reduced braking efficiency and can be a safety hazard. Therefore, the appropriate course of action would be to replace both the wheel seal and the brake shoes.
However, it is also a well-accepted practice in the automotive industry to perform repairs on both sides of an axle simultaneously when it comes to braking components. This ensures that the braking performance is even and predictable from side to side. Therefore, the preferred method to repair a wheel seal leak that has glazed the brake shoe linings would be to:
- replace the wheel seal
- replace the brake shoes on both sides of the axle
While the bearings may not be affected by the seal leak, they should be inspected for any signs of damage or wear during the repair process and replaced if necessary.
The correct option for this repair would thus be option b) replace the wheel seal and brake shoes on both sides of the axle. This approach not only addresses the immediate issue but also promotes longer-lasting repairs and ensures the safety of vehicle operation.
