Introduction
Changing the discs and pads. A 7mm Allen key is required, an unusual size.
Please note that both sides (left and right) must be changed at the same time.
A running-in period is recommended, trying not to brake suddenly for 200 km or more if there is very little braking on the route (e.g. motorway).
-
-
On flat ground, you must loosen the wheel nuts and then raise the vehicle;
-
-
Secure the vehicle with a jack stand.
-
Remove the wheel nuts and wheel to access the brake discs.
-
-
-
Open the brake fluid reservoir cap but leave the cap on so nothing falls inside.
-
With pliers you have to push the caliper piston back a little in order to remove the caliper.
-
Be careful not to damage the piston bellows.
-
-
-
You need to loosen the two caliper bolts, they are protected by two dust covers.
-
Carefully remove the two covers
-
Using a 7mm male Allen key (6 sides), loosen the two bolts. Be careful, this key size is not common!
-
-
-
Remove the caliper by pulling it outwards
-
Extract the two plates
-
The one against the piston has a clip forced into the piston, it is removed by hand.
-
-
-
Loosen the two 13 bolts on the caliper carrier
-
Pull the disc outwards, if it is seized it can be released by tapping lightly with a mallet.
-
-
-
The piston must be pushed back to provide space for the new pads.
-
When pushing the piston back, check the level of the brake oil reservoir to avoid overflow.
-
To avoid damaging the piston or its bellows, you must use a piston pusher.
-
Clean the contact surface of the hub with the disc.
-
We can clearly see the state of wear of the old disk. Take the opportunity to check that the new disk matches correctly.
-
-
-
Install the new disk
-
The two caliper carrier bolts must be reassembled with blue threadlock.
-
Tighten the two caliper carrier bolts. Tightening torque = 3 daN.m
-
-
-
Clean the contact surfaces of the brake pads
-
Put on a dust mask
-
The columns must be greased with high temperature grease.
-
To remove the columns, simply push the threaded part by hand.
-
Put the columns back in their housing
-
-
-
insert the clip of the first pad into the piston.
-
Place the second pad
-
Present the assembly on the new disc, check the correct positioning of the hook of the two pads (pink circle in photo 3)
-
-
-
Tighten the two column bolts. Tightening torque 30 Nm Replace the two dust covers.
-
Degrease the surface of the disc with brake cleaner for example.
-
Reassemble the wheel and move to the other side.
-
Once both sides have been done and the vehicle is on the ground, press the brake pedal several times to bring the pads closer to the disc.
-
Check the brake fluid level, adjust if necessary (dot 4 fluid) Close the cap
-
Running in, trying not to brake suddenly for 200 to 300 km or more if there is very little braking on the route (e.g. motorway).

Be careful at step 7, the tightening torque is not 3DaN.m but 7DaN.m. The columns are tightened to 3DaN.m but not the caliper holder screws.

Great operating mode. Precise, photos and comments very simple and effective. Thank you for your valuable help.
Question what is the thickness dimension of the disc that gives the alert that it needs to be changed?

Good morning,
Congratulations on this tutorial, it is simple, precise, explicit and effective. All I have to do now is get to work.
Question: from what minimum thickness rating should the disc need to be changed?
Sincerely
Marc
