How To Replace Emergency Brake Shoes On Ford F150

The brake system of the vehicle is particularly important for the safety of the vehicle, so the maintenance of the brake system has become the primary task of vehicle maintenance. In the braking system, many car owners only pay attention to the maintenance of the brake skin and brake disc, but ignore the parking brake shoes.

This article will use the example of replace emergency brake shoes on Ford F150 to demonstrate the whole process of replacing parking brake shoes. In addition to letting everyone understand the structure of the parking brake, it also provides a reference for some owners with strong hands-on ability to replace themselves.

Brake Shoes

The function of the brake shoe is that the brake shoe is a friction couple of the drum brake, which cooperates with the brake drum to brake the vehicle. The brake shoe assembly is the brake shoe and brake shoe in the drum brake. The brake shoe is a friction couple of the drum brake. The brake shoe bears the thrust of the actuator, the normal force and tangential force of the brake drum, and the support reaction force.

The Disassembly Method of Drum Brake Shoe:

1. Before disassembly, use a screwdriver to press the wedge upward through the bolt hole of the wheel to return the brake shoe;

2. Remove the hub cover with vw637/2 special tool, pull out the cotter pin, and remove the crown nut safety ring;

3. Remove the adjusting nut, washer and bearing of the wheel hub bearing preload, and remove the brake drum;

4. Finally, remove the brake pad.

How To Replace Emergency Brake Shoes On Ford F150

Wrench, socket, piston pressure pump and silencing paste are required to replace brake pads

1. Before replacing the Ford F150 Brake Shoes, open the cover of the brake fluid reservoir in the engine compartment to see the height of the brake fluid page. If the brake fluid page is above the maximum limit, the brake fluid should be sucked out to prevent the brake fluid from overflowing during the replacement process;

2. Prepare theFord F150 Brake Shoes to be replaced and remove the wheel on which the brake is located. Avoid scratches on wheels and vehicles during disassembly;

3. Remove the bolts of the brake caliper with a wrench and a socket, and then remove the brake skin (if there is a brake sensing line, remove the brake sensing line first). Observe whether the brake pad is excessively worn or cracked. If yes, replace it in the next step;

4. Since there will be a lot of sand or soil in the brake caliper, it is necessary to clean it with a rag, and then apply silencing paste to prevent abnormal noise during braking;

5. Use the piston pressure pump to press the piston to the position where it cannot be pressed, and then install the Ford F150 Brake Shoes on the brake caliper. After the new brake pad is installed in place (it should also be installed if there is a brake induction line), tighten the guide bolt and complete the installation;

6. After installation, cover the reservoir, step on the brake pedal and reset the brake. Then observe the brake fluid height within the appropriate height range;

7. Test run after replacement to check whether the braking effect is reflected.

When to replace the brake pads and precautions

1. under normal driving conditions, check the brake shoe every 5000 km, not only check the remaining thickness, but also check the wear status of the shoe, whether the degree of wear on both sides is the same, whether it can return freely, etc. any abnormal conditions must be handled immediately.  

2. the brake shoe is generally composed of iron lining plate and friction materials. Do not replace the shoe until the friction materials are worn out. For example, for the front brake shoe of Jetta, the thickness of the new brake shoe is 14mm, while the replacement limit is 7mm, including the thickness of iron lining plate of more than 3mm and the thickness of friction material of nearly 4mm. Some vehicles are equipped with brake shoe alarm function. Once the wear limit is reached, the instrument will give an alarm prompt to replace the shoe. The shoe that has reached the service limit must be replaced. Even if it can be used for a period of time, the braking effect will be reduced and the driving safety will be affected.  

3. when replacing, replace the brake pads provided by the original spare parts. Only in this way can the braking effect between the brake pads and the brake discs be the best and the wear be minimized.  

4. when replacing the shoe, the brake wheel cylinder must be jacked back with a special tool. It is not allowed to press back with other crowbars, which will easily lead to bending of the brake caliper guide screws and jamming of the brake pads.  

5. after replacement, be sure to step on several brakes to eliminate the gap between the shoe and the brake disc, resulting in no braking of the first foot, which is prone to accidents.  

6. after the brake shoe is replaced, the best braking effect can be achieved only after running in for 200 km. The newly replaced shoe must be driven carefully.
