I have a 2000 Tahoe with 175,000 miles on it and I just recently replaced all the metal brake lines due to leaks in old lines. I used Dorman Products Stainless Steel ones and did the hydraulic lines as well. I also replaced the ABS Pump (complete unit}, bled the
brakes several times. I then tested the braking action. When I did so, the brake pedal was firm with the engine off, but went down about an inch when pressed with the engine running. Does stop hard while driving, but brake warning light flashes and chimes while doing so and the ABS warning light comes on. Parking brake not set while testing and emergency pads were not readjusted when I replaced all brake pads and calipers in May 2023. Do i have a proportioning valve as well to consider? Could driver side grounding screws be an issue? Do I need to replace the master cylinder? Please advise as my Tahoe has been sitting since April (2024) and I need to get it up and running again. I have just discovered this Forum and registered into the website on November 15th, 2024. Please advise, thankyou!
