Refitting a caliper
1
If the caliper needs to be wound onto the brake flexi-hose (if the hose isn’t attached with a banjo bolt), then make sure the hose isn’t twisted when the caliper is fitted. You may need to slacken the hose’s connection at the opposite end. Always renew any washers used with the brake flexi-hose.
2
The mounting bolts for the caliper carrier (single-piston calipers) or caliper (multipiston) need to be tightened to a specific torque setting. This is usually quite high (60-80Nm), but check your workshop manual. Slider bolts are usually not so tight (around 30Nm).
3
When refitting a rear caliper, the handbrake linkage may need to be reconnected. Renew any clevis pins, horseshoe clips and other fittings if they are corroded and in danger of breaking.
4
Once all of the brake calipers have been refitted, top up the brake fluid in the reservoir, then bleed the brakes. The bleeding sequence usually starts the furthest away from the brake master cylinder.
