Part 5: Lubrication and Reassembly
There are two types of lube used for disc brakes:
- A disc brake lube... it should be a translucent lube that is rubber compatible. This is used for caliper slider pins.- A heavy brake grease, I use an anti-seize compound/grease with a copper additive as per the manual. The grease will not wash away like the disc brake lube will. Any component of the brakes that sees metal to metal contact gets a light coating.
DO NOT allow the lube/grease to come in contact with the pad material.
Front Caliper - Exploded view:
1 - Remove the lower slider pin. You may have to twist the slider dust boot with your fingers to break it free.
2 - Inspect the lower slider pin for rust and dirt. If it's clean, apply a very small amount of disc brake lube. DO NOT use anti-seize compound. Reinstall the slider pin ensuring the dust boot seats in the groove on the slider pin.
3 - Repeat the same for the slider pin attached to the caliper. Do not re-install it at this point.
4 - If you had removed the brake rotor, now is the time to reinstall it. Coat the surface of the hub with anti-seize then reinstall the rotor. This will make it easier to remove the rotor in the future.
5 - Apply some anti-seize compound to the caliper bracket where the retainer clips go. This will help to displace water and prevent corrosion.
6 - Install the retainer clips at each end. Be sure you put them in the same location and orientation you removed them. Be sure they are firmly seated as you will not be able to get the pads in otherwise.
7 - Lubricate the visible portions of the retainer clips with a thin layer of anti-seize. These will be in direct contact with the brake pads.
8 - Install the shims on the back of the pad in the same order they were removed. Use a light coat of anti-seize compound between the shims and on the back of the outer shim.
9 - Lubricate the small tabs on each end of the pad with anti-seize compound.
10 - I find it easier to pre-install the rear pad on the caliper bracket. If you have not removed the caliper bracket, then install the rear pad. It can sometimes be difficult to get the rear pad in place. It fits very tightly in place. Try inserting both ends simultaneously and lightly tap with a hammer until the pad is in place.
11 - If you have removed the caliper bracket/torque member earlier, reinstall it. Ensure the bolts are tightened.
12 - Install the front pad using the same procedure as step 10.
13 - With the pads in place, you can now re-install the caliper. Re-check the upper slider pin to ensure it has not gotten dirty. Clean and re-lube if necessary. Unhook the caliper from the 'hook' you made and slide the upper pin into the caliper bracket. Ensure the dust boot seats in the groove on the slider pin.
14 - Rotate the caliper downwards. Be sure it does not catch on the shims.
15 - Reinstall the lower slider retaining bolt.
16 - The caliper is now reassembled. Be sure to recheck all the bolts (4 in total) for tightness.
17 - You can now reinstall the wheel and hand tighten the lugnuts. Remove the jack stands and lower the vehicle. Torque the lug nuts with the tire on the ground... it's easier.
The process is repeated for the other brakes. There is a slightly different procedure for the rear caliper... see the next part.
One final and very important note:
Before going for a test drive, pump the brakes several times. The caliper piston may have been disturbed resulting in a loss of braking power the first time they are used. You don't want to find this out when it's too late!
