Thanks PhilSkill Very Happy

RE: emergency parking brake

Are you holding the Parking brake Switch and pressing the pedal while switching it off and on?

The Brakes should be off (retracted) from holding the switch in the release position, if they are re-applying, when is this happening? you'll hear the motor re-apply them.

RE: emergency parking brake

Does it work have you tested it ? I wanted to change my break pad and found it near impossible to release the break once you switch the engine off.

No wonder LandRover charge £261 to replace break pads.

RE: emergency parking brake

I just tried this procedure on my wife's 2012 Evoque. First, the EPB retracted but there was no audible sound, so mid-way through the caliper disassembly the EPB re-applied!

Re-attempting to release the EPB has the dash symbol flashing and the message "EPB needs recalibrating".

I repeated the procedure above until I heard the EPB release again, but I am unable to push the piston back into the cylinder ( using a G-clamp). Is there a special trick to getting the piston to retract so the caliper will fit over the new pads?

Help required as the car is now stuck on the drive, it's got dark and I've run out of patience!

Thinking about my post above, does getting the EPB into service mode, cause the calipers to fully retract the piston? Making the process of pushing the piston back (as I have done on many older cars) unnecessary?

I did try cracking the bleed nipple to avoid pushing fluid back through the ABS etc. But this didn't reduce the resistance at all - and I put as much pressure on it as I dare.

If the trick is in getting to the 'service mode' and not just releasing the EPB, is the procedure typed in the above posts correct? And what might I be doing wrong?

Again, any help will be appreciated.

Mike.

RE: emergency parking brake

Has anyone successfully changed the rear brakes? I was able to put mine in service mode, but the EPB does not retract far enough to replace the pads, just enough to allow me to remove the calliper.

The LR dealer told me they retract the brake piston electroncially, so no G clamp or 3-pin retractor tool is used.

RE: emergency parking brake

I had to change both pads and rotors. I successfully put the park brakes into service mode. After that I could compress the caliper piston back to fully retracted, before service mode you cant move them more than the amount to back off the pads on the rotors.
To clarify those instructions.
You need to have the cars ignition on. This is done by pressing the start button without your foot on the brake pedal. (If you have your foot on the brake pedal the car will start)
Press and hold the brake switch down (this is release) and wait for 2 seconds.
While still holding down the brake switch depress the accelerator pedal to full throttle and wait another 2 seconds.
Then press the start button to switch the ignition off and then on again (2 presses)
You will hear the park brake retract and it will take a few seconds, I kept the park brake and the accelerator pedal pressed the whole time.
On the instrument panel you will see the message "park brake in service mode" when the operation is complete.
You then can push the caliper pistons back.
The piston does not retract on its own. The procedure winds back the park brake which when in normal mode will prevent the piston being retracted.
If you don't have a caliper piston tool I would advise against using a clamp around the back of the caliper as the park brake motor looks to have a plastic housing. I used a gear puller to push the piston against the caliper fork instead.
After you have replaced the components use the deactivation instructions in the topix image remembering that you need to start with the ignition on and the engine not running.
I was able to buy pads and rotors for $170 all up and got the job done in just over an hour.

No need for OBD, DUB01s's instructions are spot on.
