Brake Lines - Booster to ABS (Dual Motor) (RHD) (Remove and Replace)
Correction Code 33034502
- 2025-04-11: Added step to separately add correction code 18200102 as a separate activity to the Service Visit, updated procedure and added post replacement routines.
Note
This procedure requires the A/C
Refrigerant (Recovery and Recharge) procedure to be performed. If not already
automatically added to the Service Visit, add correction code 18200102 as a
separate activity to the Service Visit.
Removal
- Recover the A/C refrigerant from the vehicle. See A/C Refrigerant Recovery and Recharge (Remove and Replace).
- Remove the 12V battery bracket beam. See 12V Battery Bracket Beam (Remove and Replace).
- Release the bolts (x4) that secure the coolant reservoir to the front crossmember (torque 6 Nm). Do not remove the reservoir at this time.
- Carefully lift up the coolant reservoir and disconnect the coolant level sensor harness.
- Release the coolant hose clamp at the coolant pump.
-
Remove the coolant hose from
the pump.
NotePinch hose with clamps and gently pry the hose off the pump. Leave hose clamps fully engaged on hose to prevent coolant spillage.
- Set the coolant reservoir aside.
-
Remove the nut (10 Nm) that
attaches the A/C line to the compressor.
NoteDiscard the O-ring and replace with a new one during installation.
- Release the fasteners (x2) that secure the fuse box to the front crossmember (torque 6 Nm).
- Release the clip that attaches the 12V battery supply cable to the fuse box.
- Remove the bolt that attaches the PT pump 1 bracket to the body.
- Set PT1 pump and fuse box aside.
- Release the clip that secures the RH body harness to the bottom of the front crossmember.
- Release the nut that secures the front drive unit ground strap to the body (torque 6 Nm), then release the clip that secures the intelligent battery sensor (IBS) harness to the body.
- Disconnect the high side A/C PT sensor connector and the LH front impact sensor harness and set the harness aside.
- Release the clips (x3) that secure the brake lines to the LH frame rail.
- Release the clips (x2) that secure the brake lines to the front crossmember.
-
Loosen the nuts (x2) (torque
18 Nm) that attach the brake lines to the master cylinder, and then remove
the brake lines from the master cylinder.
NotePut absorbent material below the master cylinder to catch residual fluid.
- Place suitable absorbent material underneath the ABS module and brake lines.
-
Release the front brake
lines from the ABS module (torque 23 Nm).
CAUTIONIf brake fluid is spilled on a painted surface, wash off immediately with clean water.
- Plug the brake line connections to prevent contamination.
- Remove the brake line from the LH frame rail.
- Remove the 2 line brake bundle from the vehicle.
Installation
Installation procedure is the reverse of removal, except for the following:
- Recharge the A/C refrigerant system. See A/C Refrigerant Recovery and Recharge (Remove and Replace).
- Perform a coolant air purge. See Cooling System - Partial Refill and Bleed.
- Perform a cooling system thermal test. See Cooling System - Thermal Test.
- Perform the brake bleed procedure, including the brake stiffness test. See Bleed or Flush Procedure - System (Remove and Replace).
