Hi all, I replaced the calipers and pads and flex hoses in the rear. (1973 1,7)
Old brake fluid from reservoir removed with siringe and filled with new fluid. I did set the clearance on the inner and outer on both sides. Then I did bleed the brakes and checked the clearance again (was still OK) Now the proportioning valve part....do I need someone to push the pedal to the floor, keep pedal at floor and then I bleed again while pedal is down? Or does it work another way ? Or is it not needed after what I already did ? Thanks for your reply ! |

One problem with vacuum bleeding is you pull air around the threads on the bleeders. Putting air over the fluid pushes it through the system and is very effective at purging the proportioning valve as well.
I've never tried the gravity method, it makes perfect sense though. |
