BRAKES

Classics Monthly - - Jaguar X-Type -

1 The calipers on the X-Type are the sin­gle-pis­ton slid­ing de­sign found on most mod­ern cars. First step in re­mov­ing the pads is to un­bolt the caliper slid­ers... 2 ... af­ter which the caliper can be lifted away, leav­ing the pads in the car­rier. It was here that we dis­cov­ered the prob­lem, since the out­board brake pad took some force to re­move from the car­rier. 3 Early X-Types like ours have a hex socket cast into the caliper pis­ton which means you can get away with­out us­ing a spe­cial tool to wind the pis­ton back – just squeeze it as you turn it with a big hex bit. Do­ing this proved that the pis­ton wasn’t seized, while wind­ing the pis­ton back a touch makes it eas­ier to re­assem­ble the caliper af­ter­wards. 4 The car­rier bracket is held by two 13 mm bolts on the rear face. 5 Even with the car­rier un­bolted, the out­board brake pad was still stuck in place, which ex­plains the burn­ing smell. 6 You can see here how the slid­ing faces are cov­ered in a build-up of cor­ro­sion and grot, which is pre­vent­ing the pads from mov­ing freely.

7 A hefty dose of brake cleaner and a wire brush kicked off the clean-up... 8 ... fol­lowed by a half-round file to re­ally clean up the curved slid­ing faces. 9 A drop of thread­lock was used on the car­rier bolts when re­assem­bling be­fore torque­ing them up to 70Nm. 10 A thin coat­ing of copper grease was used when re­in­stalling pads and they were mov­ing prop­erly so ev­ery­thing could be re­assem­bled, with the caliper slid­ers torqued to 32Nm. It’s been fine since, even with a heavy weight on the back of the car.
