i was replacing my front brakes (on a 75 914) and in the process i broke the hydroplic brake fluid line to the caliper -drivers side. i bought a replacment original metal hydrolic brake line and installed it.
i installed new rotors, calipers and pads for the front -the back is good to go, does not need pads or brake adjustment. problem is, when i bled the brakes, nothing seems to happen -no pressure. i've bled brakes a thousandmillion times and just don't get it. any help would be great. what can i do to get some presure in these brakes?

I've kept the reservour filled, but i have not bled the master -something i've never done before.
I've done a lot of reading of articles on this website and I still don't get it. I guess bleed bleed bleed is the best answer for this. How do I bleed the master cylinder while it's attached to the car? do I need to bleed the proportioning valve. Will switching to a T really make a huge difference in my braking? Please help! |

Please explain your brake bleeding procedure - it may help with finding out where things are going wrong.

this is the process i've used for bleeding brakes.
in order; passenger rear driver rear passenger front driver front. 2 person team. first way -pump the brake until all the air bubbles stop. once i see no air bubbles i tell the person pumping the brake pedal to hold it down. then i tighten the nipple on the caliper and move on to the next. second way -i have the pedal person pump the pedal 5 times and hold down, then i turn the nipple and let the air out, then close. repeat until no air comes out and on to the next. i always make sure the reservour is filled with new fluid. i still have a spongy pedal. what kills me is that all i did was replace the two front calipers and one line I broke that goes to the drivers side caliper. this really shouldn't be this big a pain! |
