Hey guys, after reviewing all the great previous diy posts on brake rotor changes, I have a few outstanding questions:
  • Do I need to apply anything to the threads of the hub retaining screws, for example: anti-seize or thread-lock? or is this screw fitted dry?
  • Does the e-brake need need to bedded/burnished if the shoes are not being replaced? If so, what is the process?
  • Is blue thread-lock used on the caliper bolts? My pads did not include new bolts so I will be reusing the existing ones.
Thanks in advance!

OK so I combed the interweb and found some answers, maybe someone else can benefit from this:
- You should use anti-seize on the threads of the disc retaining screws. They are very prone to corrosion.
- You should use blue thread lock on the caliper bolts if you are reusing the old ones.

- I'm still NOT SURE IF you need to bed-in the rear discs after replacing them, even if the shoes are not replaced. Here are instructions I found for the previous gen RRS.

1) With the Engine running, press the brake pedal fully on and off 3 times. On the third press, hold the brake pedal down.
2) With the brake pedal still in the down position, pull the EPB switch upwards 4 times and then downwards 3 times. This must be completed within 10 seconds.
3) Your dash display will then show ‘Park Brake Bedding Cycle Active’ or something similar. If it hasn’t, then release the brake pedal and try again.
4) You need to ensure that you are on a clear piece of road or land as this procedure needs to be completed 10 times.
5) Drive at least 19mph and maximum of 29mph and then apply the EPB switch until you stop. You then need to wait for 60 seconds or drive for 1 mile (to allow the brakes to cool down before repeating the process.
Note: If you stop the engine or you drive over 30 MPH, the bedding in process will be cancelled.
6) At the end of the 10th time, the bedding in mode will automatically finish.

Well, I ran into a complete STOP today while changing the rear brakes b/c I cannot retract the rear caliper. I lost all patience with F-ing JLR today. I like working on cars, I've changed brakes on every vehicle I've ever owned, and I was reduced to counting to 10 at least a half-dozen times as I tried to find my way through the labyrinthine sequence to get this job done.

-put the vehicle in extended height mode before jacking...make sure to read the manual, gotta hold that button for >3 sec.
-gotta guess where to jack the vehicle if I want to put the jack stands under the only "approved" support points.... thank god the control arms have ridges to hold the head of the floor jack.
... oh-crap the jack stands are too short, no biggie I'll put them up on blocks.
-put the tranny in N by accessing the secret door that only little girl fingers can get to.
-use the super-secret method for entering the e-brakes into "maintenance mode": {ignition on, push ebrake lever for 2 sec, then add pushing acc pedal 2 more sec, then turn ignition off and on, then release acc pedal and ebrake lever: dashbord says "maintenance mode"}
-make sure to remember to loosen the brake reservoir cap, hidden under that useless POS plastic trim cover.
- attempt to squeeze the caliper back - NOPE won't retract.
- attempt to screw the caliper back - NOPE, rotates but won't retract.
- search google - AH YES, the info I needed: only the dealer's computer can retract the ebrake.
- reverse the above 900 steps.
- Grab hard liquor.

Thanks for the suggestion do you have one and have you used it for retracting the ebrake? The product description doesn't say anything about the ebrake and the reviews are not too good.

Yes, I have it and it does the e-brake, clear service interval. Does not change any car configurations or settings.

I took the F-Type into a local JLR Indy place yesterday for new front Rotors and Pads, and new rear Pads. They hooked it up to the Computer and put it into service mode, no problem, then they couldn’t get it OUT of service mode, they spent hours trouble shooting and discovered there was corrosion somewhere preventing them from doing so.

yes, I know this isn’t a Jag forum, just passing this along to help someone troubleshoot problems in future.

I had the same problem. Front pad installation went smooth and easy using a caliper compression tool. The rears would not move. Then I remembered they may need to be turned while compressing. My Mercedes required turning while compressing. It took almost an hour per rear caliper slowly compressing/turning before I was able to get the pads in place. I was not aware of any parking brake retraction at the time. Maybe that would have reduced the time to compress the rear calipers. I'm ready for another set of pads and will replace the rotors this time. Hopefully no issues

To do any work on the rear brakes you need retract the parking brake by entering the emergency brake service mode. Here's the procedure taken from JRL workshop manual. I have standard brakes fitted, I don't know if the procedure is the same for Brembo?

This procedure requires the vehicle in the Park or Neutral position, with the ignition turned ON (the engine must be OFF) and the parking brake system in Service Mode.
Once the rear brake pads or brake discs have been installed, the Service Mode must be cancelled.

Activate service mode:
1. Press and hold the parking brake switch in the release position.
2. Wait 2 seconds.
3. Press and hold the accelerator pedal in the wide open throttle position.
4. Wait 2 seconds.
5. Turn the ignition Off and back On immediately.
(An audible noise will be heard to confirm that the parking brake has been released in Service Mode.)
6. Release the accelerator pedal and release the parking brake switch to the neutral position.

Deactivate service mode:
1. Press and hold the parking brake switch in the apply position.
2. Wait 2 seconds.
3. Press and hold the accelerator pedal in the wide open throttle position.
4. Wait 2 seconds.
5. Turn the ignition Off and back On immediately.
(An audible noise will be heard to confirm that the parking brake has been released from the Service Mode.)
6. Release the accelerator pedal and release the parking brake switch to the neutral position.

This worked for MY2013 with the Brembo. I wonder if this process works for more recent models (2018-2019)?
