Installing front brake calliper

Information 

Do not bend the brake lines.

• Secure brake line holders at the wheel carrier  .
• For easier access to the holders, turn in the wheel carrier as required  .

→ Fit new pad retaining springs

Information 

• Never use an impact bolter to loosen and tighten the brake calliper on the wheel carrier  .
• Carry out a visual inspection on the thread for the brake calliper and blow it out carefully if necessary using compressed air. Use goggles! 
• Replace screws for securing the brake calliper  .

1. Check that all parts are in perfect condition (visual inspection) and replace them if necessary.
2. Installation is performed in reverse order. Pay particular attention to the following:

   Tightening torques:

   Brake calliper to wheel bearing housing (17-inch - black): Tightening torque 196 Nm (145 ft. lb.) 

   Brake calliper to wheel bearing housing (18-inch - red/silver): Initial tightening 30 Nm (22 ft. lb.) Final tightening +90° 

   Brake calliper to wheel bearing housing (PCCB): Initial tightening 30 Nm (22 ft. lb.) Final tightening +90° 

   Brake line to brake calliper (grey cast iron): Tightening torque 20 Nm (15 ft. lb.) 

   Brake line to brake calliper (PCCB): Tightening torque 14 Nm (10.5 ft. lb.) 

   Holder to wheel bearing housing: Tightening torque 10 Nm (7.5 ft. lb.) 

   To make it easier to install the brake calliper, assembly pins T10439  → Assembly pin for brake calliper  can be used (not for 17-inch brake calliper).

   • Screw in bottom brake calliper screws several turns by hand (this protects the thread!).
   • Remove assembly pin and screw in top brake calliper screw several turns by hand (this protects the thread!).
   • Screw in both brake calliper screws fully and tighten to the specified tightening torque.
   WARNING: Improper handling of fluid-carrying lines

   • Escaping fluid
   • System malfunction
   • Risk of escaping fluid catching fire

   → Do not kink, crush or twist the line

   → Avoid torsion and shearing

   → Fit the line carefully

3. Check line routing of brake hose -1-  .

   When doing this, check that the brake hose -1-  (as shown) is at its original position in the grommet -2-  and is not touching the spring strut.
