The handbrake pads on a Jaguar E-Type are found in just the rear subframe and function on the top rated of the discs. Even though this will make access hard it is quite possible to adjust the brake pads without the need of removing the subframe, saving sizeable price tag/time if you know how to do it. Most of the occupation is rather simple and the only element wherever entry can can make points tough is the refitting of the retractor plate made to pull the calipers apart when the brakes are released. This far too can be reached without having way too considerably hard work with the appropriate approach. These instructions use to all 6 cylinder designs fitted with self-changing handbrakes which is all but the pretty early versions. They are a health supplement to the guidelines in the Jaguar Workshop Handbook.
The picture shows the forward side of the subframe with a rear footbrake caliper in the middle and the entrance of the differential casing in the history at the bottom remaining. The handbrake calipers are hooked up to the footbrake calipers by indicates of two pivot bolts. These bolts also keep the retractor plate in position with its two tines which arrive at throughout to the two caliper halves.
The approach is as follows:
1. Get rid of split pin and clevis pin linking the running lever to the handbrake linkage.
2. Fold down the locking tabs and eliminate the 7/16″ pivot bolts, lock tab and retractor plate.
3. Press the caliper more than the top rated of the disc in the direction of the back again of the auto. The caliper can be withdrawn from the subframe by way of the centre opening at the back of the subframe.
4. Loosen the 5/16″ nuts clamping the pads to the carriers – there is just sufficient house amongst the reinforcing ribs to swing a 12 issue ring spanner. In the unlikely event that the clamp bolts usually are not badly rusted you can then slide the previous pads out with the help of some tapping. It is additional possible you will be entirely getting rid of the bolts and replacing these at the identical time.
5. Fit the new pads taking care to mount them the appropriate way spherical – the triangular edge upwards and the chamfer toward the adjuster bolt which backlinks the two caliper halves.
6. You will now find that there is not sufficient clearance in between the pads for the disk and you will need to have to reset the self-altering mechanism. Simply maintain one of the caliper halves and rotate the other anti-clockwise to unscrew the adjuster till the interior faces of the pads are 12 mm aside.
7. Now you happen to be ready to reinsert the calipers. Force them back again in and all around the top rated of the disk the way they came out.
8. Line the retractor plate up with the two mounting holes, place the locking tab on top rated and insert the pivot bolts into the holes ideally obtaining the holes in the handbrake calipers with some even handed wiggling. Gently tighten them but not totally as you will likely be taking them back again out.
9. This is wherever the trouble occurs. In all likelihood the tines of the retractor plate will not line up with the holes in the leading of the calipers. If the subframe is off the automobile this is not a issue but with the subframe on there is no way you can get just about anything in there to bend the tines to get them in the holes. But you should not despair. Get an inspection mirror this sort of as dentists use and take a shut glance to see in which route each individual tine is out and by how far. Make a notice of this, unscrew the pivot bolts and take the retractor plate back again out. Bend the tines according to your estimates and then reinsert. You might have to do this a pair of instances but when you have it right you will be able to reach in over the tines with a screwdriver and press them down into the holes.
10. Now you can tighten the pivot bolts adequately and press up the locking tabs.
11. Pull the working lever continuously right until the ratchet of the self-modifying mechanism stops clicking.
12. Refit the clevis pin linking the running lever to the handbrake linkage and in shape a new split pin.
13. Change the handbrake according to the manual as necessary.
