Replacement steps
1. Preparation
Make sure the vehicle is parked on flat, solid ground, and tighten the handbrake.
Place a wooden block under the diagonal tires to prevent the vehicle from slipping.
2. Remove the tires
Use a jack to jack up the vehicle and remove the tire on the side that needs to be replaced with a boot.
3. Remove the caliper
Use a 17mm wrench to remove the caliper set bolt, gently pull it outward and pull up the caliper so that it is detached from the brake disc.
Hang the caliper with wire to avoid deformation or damage caused by overhanging.
4. Remove the old dust jacket
Use a screwdriver to pry off the clamp of the boot and remove it.
If the dust jacket is tight, you can use pliers to gently clamp the dust jacket and carefully pull it out.
5. Clean up and inspect
Use a clean cloth or paper towel to clean the caliper piston and the inside of the dust and dirt.
Check the piston and oil seal for damage, if so, it needs to be replaced.
6. Install a new dust jacket
Place the new boot over the piston to make sure it fits snugly.
Use the snap ring pliers to install the snap ring in place and secure the dust jacket.
7. Reinstall the caliper
Reattach the caliper to the brake disc and tighten the set bolt using a 17mm wrench.
Make sure the caliper is securely installed and not loose.
8. Install the tires
Reinstall the tire to the wheel hub and tighten the bolts using the tire sleeve.
Lower the jack to ensure that the vehicle lands smoothly.
9. Inspection and testing
Check that all mounting parts are firm and not loose.
Start the vehicle and lightly apply the brakes a few times to make sure the brake system is working properly.
Precautions
Safety first: During operation, ensure the stability of the vehicle and avoid accidents.
Cleaning: Before installing a new boot, make sure the inside of the caliper and the piston surface are clean and free of dust and dirt.
Lubrication: When installing a new boot, apply the right amount of brake fluid to the piston to reduce friction.
Professional help: If you are unsure about the procedure, it is recommended to seek the help of a professional technician.
With the above steps, you can successfully replace the brake caliper boot to ensure the normal operation of the braking system and the safe driving of the vehicle.
