| 4 | Remove front wheels. | AR40.10-P-1102A | |
| 5 | Release and disconnect electrical connector (3) of brake lining wear sensor (S10/2) from brake caliper (2). | When removing brake linings (4) at front right. | |
| 6 | Remove electrical wiring harness of brake lining wear sensor (S10/2) from brake caliper (2). | When removing brake linings (4) at front right. | |
| 7 | Drive out bolts (7) using a suitable tool and remove. | ||
| 8 | Unscrew screw (8), replace with guide pin, and tighten guide pin slightly. | Fig 1 | |
| 9 | Unscrew screw (9), replace with guide pin, and tighten guide pin slightly. | Fig 1 | |
| 10 | Push brake caliper (2) with connected brake hose to side onto guide pin. | Do not stretch, crush or kink the brake hoses and brake lines. This leads to damage to the brake hoses and brake lines, and it can impair their function. |
|
| 11 | Remove brake linings (4) from brake caliper (2). | ||
| 12 | Unclip spreader spring (5) from brake caliper (2) and remove. | ||
| 13 | Pull brake lining wear sensor (S10/2) out of backing plate of brake lining (4). | When replacing brake linings (4) or when replacing brake lining wear sensor (S10/2). |
|
| 14 | Press back brake pistons with pusher tool. | ||

| AR42.10-P-0230S | |||
| 17 | Check brake caliper (2) for damage. | If there is a problem, ↓ Replace brake caliper (2). |
|
| AR42.10-P-0070SA | |||
| Install | |||
| 18 | Clean contact surfaces of brake linings (4) at brake caliper (2) and at brake pistons. | Do not use sharp-edged or pointed objects. Otherwise, the brake caliper (2) and the dust boots on the brake pistons will be damaged. |
|
| Assembly cleaner | *BR00.45-Z-1028-04A | ||
| 19 | Insert brake lining wear sensor (S10/2) into backing plate of brake lining (4). | When replacing brake linings (4) at front right or when replacing brake lining wear sensor (S10/2). | |
| 20 | Install spreader spring (5) in brake caliper (2). | ||
| 21 | Insert brakepads (4). | ||
| 22 | Slide brake caliper (2) onto brake disk (6). | Do not stretch, crush or kink the brake hoses and brake lines. This leads to damage to the brake hoses and brake lines, and it can impair their function. The brake line pieces (99) of the brake hoses must not be bent. Replace the affected brake hoses with damaged brake line pieces (99) immediately. If brake line piece (99) is damaged, ↓ replace affected brake hose. |
