Re: How to bleed ABS brakes
first off did you remove any of the sensors? if not don't mess with them. Did you release the pressure on the ABS system prior to doing the brake job ? if not then you more than likely have air in the abs.
BRAKE BLEEDING (WITH ABS BRAKES)
ABS system bleeding requires conventional bleeding methods plus use of the DRB scan tool. The procedure involves performing a conventional bleed, followed by use of the scan tool to cycle and bleed the HCU pump and solenoids. A second conventional bleed procedure is then required remove any air remaining in the system.
(1) If a new master cylinder is to be installed, bleed cylinder on bench before installing it in vehicle.
(2) Wipe master cylinder reservoir and cap clean before removing cap. This avoids having dirt fall into fluid. Then fill reservoir with Mopar brake fluid.
(3) Perform conventional brake bleed as described in steps (4) and (5).
(4) Bleed master cylinder and combination valve at brake line fittings. Have helper depress and release brake pedal while bleeding cylinder and valve.
(5) Bleed wheel brakes in recommended sequence which is: right rear; left rear; right front; left front. Bleed procedure is as follows:
(a) Attach bleed hose to caliper bleed screw. Immerse end of hose in glass container partially filled with brake fluid. Be sure hose end is submerged in fluid (Fig. 3).
(b) Have helper depress and hold brake pedal to floorpan.
(c) Open bleed screw 1/2 turn. Close bleed screw when brake pedal contacts floorpan. Do not pump brake pedal at any time while bleeding. This compresses air into small bubbles which are distributed throughout system. Additional bleeding operations will then be necessary to remove all trapped air from the system.
(d) Repeat bleeding operation at each wheel brake unit fluid entering glass container is free of air bubbles. Check reservoir fluid level frequently and add fluid if necessary.
(6) Perform HCU bleed procedure with DRB scan tool as follows:
(a) Connect scan tool to ABS diagnostic connector. Connector is under carpet at front of console, just under instrument panel center bezel.
(b) Select CHASSIS SYSTEM, followed by TEVES ABS BRAKES, then BLEED BRAKES. When scan tool displays TEST COMPLETE, disconnect scan tool and proceed to next step.
(7) Repeat conventional bleed procedure described in steps (4) and (5).
(8) Top off master cylinder fluid level and verify proper brake operation before moving veh
Hope this helps
