Set up the brake rotor to the wheel hub. Use the 18 mm socket to tighten the two bolts to 140 Nm (103 ft-lb).
Set up the caliper to the caliper provider. Use the 13 mm socket to tighten the two bolts to 24 Nm (18 ft-lb).
| Description | Torque |
|---|---|
| Steering knuckle to caliper provider | 110 Nm (81 ft-lb) |
| Wheel hub to brake rotor | 140 Nm (103 ft-lb) |
| Caliper provider to caliper | 24 Nm (18 ft-lb) |
Reattaching the Brake Strains and Sensors
After including the struts and different elements again into place, it’s time to reattach the brake strains and sensors.
- Find the brake strains. The brake strains are usually fabricated from steel and run from the grasp cylinder to the brake calipers. They are often recognized by the rubber hoses that join them to the calipers.
- Disconnect the brake strains. Use a wrench to loosen the bolts that safe the brake strains to the calipers. Watch out to not harm the brake strains or the bolts.
- Take away the sensors. The sensors are small, spherical gadgets which might be connected to the brake strains. They are often eliminated by hand or with a small wrench.
- Examine the brake strains and sensors. Search for any indicators of injury, corresponding to cracks or leaks. In case you discover any harm, change the brake strains or sensors.
- Clear the brake strains and sensors. Use a clear material to wipe away any filth or particles from the brake strains and sensors.
- Apply brake grease. Apply a skinny layer of brake grease to the brake strains and sensors. This can assist to stop corrosion and guarantee a superb seal.
- Reattach the sensors. Hand-tighten the sensors onto the brake strains. Don’t overtighten the sensors, as this might harm them.
- Reattach the brake strains. Tighten the bolts that safe the brake strains to the calipers. Don’t overtighten the bolts, as this might harm the brake strains or the calipers.
- Bleed the brakes. Bleeding the brakes is a technique of eradicating air from the brake strains. This have to be accomplished after any work is carried out on the brake system.
To bleed the brakes, observe these steps:
- Open the bleeder valve on the caliper furthest from the grasp cylinder.
- Have an assistant pump the brake pedal a number of instances.
- Shut the bleeder valve.
- Repeat this course of for every caliper, beginning with the caliper furthest from the grasp cylinder and dealing your approach to the caliper closest to the grasp cylinder.
Tightening and Torquing Specs
To make sure correct performance and security, adhere to the next tightening and torquing specs:
| Part | Tightening Torque |
|---|---|
| Strut to Knuckle Bolts | 47 ft-lbs |
| Sway Bar Finish Hyperlinks | 22 ft-lbs |
| Strut Mount to Physique Bolts | 18 ft-lbs |
| Strut High Nut | 51 ft-lbs |
| Wheel Lug Nuts | 89 ft-lbs |
It’s essential to make use of a torque wrench to realize these exact specs. Tightening the nuts and bolts too loosely can compromise the strut’s efficiency and security, whereas overtightening can harm the elements.
At all times consult with the automobile’s service handbook or seek the advice of a professional mechanic for particular directions and security precautions associated to your particular BMW mannequin.
Ignoring these tightening and torquing specs can result in untimely put on and tear, decreased efficiency, and even potential security hazards. By following these pointers, you’ll be able to be certain that the strut alternative is finished appropriately and your BMW operates safely and effectively.
