Caution: For safety reasons, the brake pressure modulator valve assembly must not be repaired, the complete unit must be replaced. With the exception of the EBCM, no screws on the brake pressure modulator valve assembly may be loosened. If screws are loosened, it will not be possible to get the brake circuits leak-tight and personal injury may result.
Notice: When removing the brake pressure modulator valve, protect the vehicle exterior from possible brake fluid spillage. Brake fluid can cause damage to painted surfaces.
Important: Note the locations of the brake pipes in order to aid in installation.
Notice: Be careful not to damage the EBCM seal when removing the EBCM.
Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.
Tighten
Tighten the bolt that connects the BPMV (4) to the lower mounting
bracket (3) to 10 N·m (7 lb ft).
Caution: Make sure brake pipes are correctly connected to brake pressure modulator valve. If brake pipes are switched by mistake, wheel lockup will occur and personal injury may result. The only two ways this condition can be detected are by using a Scan Tool or by doing an Antilock stop.
Important: If a new BPMV is being installed, remove the shipping plugs from the valve openings during the next few steps when ready.
Tighten
Tighten the master cylinder brake pipe fittings to 24 N·m
(18 lb ft).
Tighten
Tighten the wheel cylinder brake pipe fittings to 24 N·m
(18 lb ft).
