Important: Thoroughly wash all contaminants from around the electric hydraulic control unit (EHCU). The area around the EHCU MUST be free from loose dirt to prevent contamination of disassembled ABS components.
Disconnect the three electrical harness connectors from the electronic brake control module (EBCM).
Important: Make sure that brake lines are tagged and kept in order for proper reassembly.
Disconnect the 5 brake lines from the brake pressure modulator valve (BPMV). When looking at the brake pipe port face of the BPMV, the ports are assigned as follows:
Upper Left--Left Front Output.
Upper Middle -- Right Front Output.
Upper Right--Rear Output.
Lower Left--Master Cylinder Secondary/Front Input.
Lower Right--Master Cylinder Primary/Front Input.

Thanks. Keep updated for any more query. You can rate this solution and show your appreciation.

Brake system


I have no idea why people change a master

Take one apart some time & just clean out the
moisture & move on to bleeding all four corners
BEFORE any other work

Then replace rubber hoses,fabricate brake tubing &
replace rusted calipers etc

You need a helper in the car & motor running to bleed !!

Lets get your head into the game here
If it was the brake booster-- is that not common to all
four corners & the back is okey

Also you have the motor running, so you have already tested the
booster

Could you have two bad flex hoses--- yes
Could you have two bad calipers ---yes
Could the HCU (hydraulic control unit-abs) be
all rusted inside & an issue--yes

I hve a 96 chevy 1500 4wd with brake issues. ABS light is on in the dash. Have replaced both frt calipers, pads, hoses. Replaced rear brakes and drums. Replaced master cylinder. Bled two quarts of...


you may have air trapped in the ABS EHCU. Did you use this procedure?

Bleeding the EHCU

Bleeding the EHCU requires the use of the TECH-1 scanner or its equivalent and the appropriate cartridge. Additionally, 3 tools, J-39177 or equivalent, are required. Bleeding cannot be performed without this equipment.
The EHCU must be bled after replacement or if air is trapped within the unit. It must be bled after bleeding the master cylinder and before bleeding the individual wheel circuits.
The Internal Bleed Valves on either side of the unit must be opened 1 / 4 - 1 / 2 turn before bleeding begins. These valves open internal passages within the unit. Actual bleeding is performed at the two bleeders on the front of the EHCU module. The bleeders must not be opened when the system is not pressurized. The ignition switch must be OFF or false trouble codes may be set.
  1. Open the internal bleed valve 1 / 4 - 1 / 2 turn each.
  2. Install one tool J-39177 on the left bleed stem of the EHCU. Install one tool on the right bleed stem and install the third tool on the combination valve.
  3. Inspect the fluid level in the master cylinder, filling if needed.
  4. Slowly depress the brake pedal and hold it down.
  5. Open the left bleeder on the front of the unit. Allow fluid to flow until no air is seen or until the brake pedal bottoms.
  6. Close the left bleeder, then slowly release the pedal. Wait 15 seconds.
  7. Repeat Steps 4, 5 and 6, including the 15 second wait, until no air is seen in the fluid.
  8. Tighten the left internal bleed valve to 5 ft. lbs. (7 Nm).
  9. Repeat Steps 3-7 at the right bleeder on the front of the unit.
  10. When bleeding of the right port is complete, tighten the right internal bleed valve to 5 ft. lbs. (7 Nm).
  11. Remove the 3 special tools.
  12. Check the master cylinder fluid level, refilling as necessary.
  13. Bleed the individual brake circuits at each wheel.
  14. Switch the ignition ON . Use the hand scanner to perform 3 function tests on the system.
  15. Carefully test drive the vehicle at moderate speeds; check for proper pedal feel and brake operation. If any problem is noted in feel or function, repeat the entire bleeding procedure.

I have an ABS light problem on my GMC mod 1998, when i change the rear diferentiel , is there any link to the front break


what is the nature of your problem light staying on going off coming on? the problem started after the rear end change? The EHCU has 2 lines going into it and 3 out. The 2 "in" are from the combination valve, 1 for rear system and 1 for front system. The 3 "out" are split into 1 for rear brakes and 2 for front brakes. check this out and let me know to further help you

1995 GMC Sierra 3500 both front brakes locks up after driving a few miles have replaced all but the EHCU.


That was a bad year for anti-lock units. GM changed this around 2000 or so.
