I just completed the 5 lug conversion on the front and I can't get any brake pedal pressure. I've bled the system from the back pass. first, driver rear second, front pass. third and front driver last. I have clear fluid all the way through the system and no bubbles.
The front calipers are rebuilt with all new seals. I pressed on the pedal slowly with the bleeder valve open and can see fluid moving towards the catch bottle. There are no leaks anywhere. I'm stumped, I'm wondering if the master went bad somehow and it wont build pressure. They worked great before the conversion. |
