05 equinox had a collasped front brake line replace both front lines both calipers
I replace both front brake lines , calipers, rotors and pads. I bleed it with vehicle off and get good pedal.... turn the vehicle on and hardly have any pedal at all.... any help or suggestions
If you have no leak it more than likely is still trapped air. Did you let master cylinder run dry, if so you need to bleed. Or maybe got air in back lines and need to bleed. Did you check all lines and hardware for leaks? You'll find it just takes time and search and searching!
I ran 5 bottles through it, it then took to a mechanic shot with a scan tool to activate abs and they ran 3 bottles through it and still has no pedal while running they don't know I don't know and charged me 300
Recheck calipers and make sure they are moving freely on guide pins. If just piston side of caliper is working that is why you have brake pedal with engine off but when you start vehicle and the outside pad is not working because caliper is not sliding on guide pins could be your problem.
Also make sure the pads are setted in correctly and not binding up.
If all things are sealed than I would lean toward bad master cylinder. The seals being bad and not allowing the cylinders to build pressure because of 'blow by'. If you can see there may be fluid where pedal goes into master cylinder, under dash, but not always is this the case. Let us know what u find...curious!
