9.14 REPACKING DRIVESHAFT GREASE
The driveshafts should be stripped, cleaned and re-greased every 10 hours of running. To do this, remove the
driveshafts from the car, then remove the CV boot clips and slide them back away from the housing. Remove
both housings and clean all the old grease in a wash tank. When re-assembling the driveshafts a set amount
of grease should be applied to each end of the driveshaft, the amount is listed below. New clips should be
fitted to the CV boots to prevent them from coming off.
SR3 Driveshaft Grease (Per Joint): 70g
Total 400g Driveshaft Grease Part Number: TO0008
9.15 REPLACING CALIPER SEALS
1. Extend pistons for easy removal unbolt callipers, take out brake pads and place a block in the
caliper to prevent pistons from falling out. Then pump the pedal until all pistons are extended 10-
15mm (or carefully use an airline in the fluid inlet if the callipers are off the vehicle).
2.
Remove calipers from vehicle.
3. Remove pistons by hand do not use pliers or any kind of tool that could damage the outside of the
piston.
4. Remove old seals from the caliper body.
5. Clean and inspect the pistons. You are looking to remove all contaminates from the outside of the
pistons and ensure that there is no scratches/damage. You can polish the pistons to get the surface
perfect.
6. Thoroughly clean the calipers use an airline to blow out any contaminates from piston bore and
fluid ways,
7.
Grease the new seals and pistons, recommended product for this is:
Rocol Sapphire Aqua-Sil
Alternately soak the seals in brake fluid for 24hrs prior to installation and lubricate the pistons with
brake fluid.
8. Install the new seals in the caliper body ensure that the seal is seated correctly to prevent
damaging them when pushing the pistons in.
9. Push the pistons in by hand, the seal should offer minimal resistance when the piston goes in square.
If resistance is high, the seal is not seated correctly.
10.
Install calipers and bleed brakes. Make sure the outside of the calipers are dry then leave overnight.
Check brake calipers after they have been left overnight for any leaks.
