Manual Bleeding
- Bleed BPMV after master cylinder, but before wheel cylinders and calipers. Ensure ignition is off. Install 2 Combination Valve Depressors (J-39177) on High Pressure Accumulator (HPA) bleed valves. See Fig 1
. Install one combination valve depressor on combination valve bleed valve. Rotate 2 BPMV internal bleed screws 1/4-1/2 turn counterclockwise. See Fig 2
.CAUTION: If internal bleed screws are left open, hydraulic fluid will by-pass accumulator, and hydraulic pressure will be lost.
- Slowly apply brake pedal pressure and hold. Open left bleed screw on front of BPMV. See Fig 1 . Leave left bleed screw on front of BPMV open until all air is expelled or brake pedal is fully applied. Close left bleed screw on front of BPMV. Wait 15 seconds. Repeat this step until all air is purged from BPMV, then close left internal bleed screw on BPMV. See Fig 2 .
- Slowly apply brake pedal pressure and hold. Open right bleed screw on front of BPMV. See Fig 1 . Leave right bleed screw on front of BPMV open until all air is expelled or brake pedal is fully applied. Close right bleed screw on front of BPMV. Wait 15 seconds. Repeat this step until all air is purged from BPMV, then close right internal bleed screw on BPMV. See Fig 2 .
- Remove combination valve depressors from High Pressure Accumulator (HPA) bleed valves. Remove combination valve depressors from combination valve bleed valve. Ensure master cylinder fluid reservoir is full.
- Bleed wheel cylinders and calipers as necessary. Brake bleeding sequence is as follows: right rear, left rear, right front, left front. Use DOT 3 brake fluid only. Evaluate brake pedal feel and braking performance. Repeat bleeding procedure if necessary.
