This is where I put my valve. Easy to install, easy to reach, and just as protected as other fragile things under the car
Before fit all together, I did a "presentation" of all items. However, the presentation needs two phases; one without tight anything and another with all tighted.Did you use spacers to achieve your clearances?
thanks, I'll try and I will tell you know how it well...All I can tell you is that I use a Power Bleeder contraption to pressurize my brake fluid reservoir/MC. With normal brakes I then just started opening the bleeders at the calipers and rear drum brake cylinders and the the fluid would run out, then I would tighten them after the bubbles and rusty fluid had been purged. After installing the rear discs, nothing would come out of the rear calipers, I had to have someone pump the pedal to make the fluid come out of the rear calipers. PJRomano had installed rear discs shortly before I did and he said that he just left his proportioning valve set at the 50% it was set at when he got it, so I did the same thing.
I have no idea why simple pressurizing of the system would not work with the prop valve or why pumping the pedal does. When you are done and you've done everything more or less correctly, your brakes will be amazing and should make contact with only about an inch of pedal movement.
I've heard it said by our main guru, RallyBob, that you should bleed all the fluid out of your brake system once a year to purge the rusty, oxygen saturated, fluid out. Before I installed the rear discs I did this every year and, yes, lots of rusty fluid came out, even though all my brake components were brand new, except for the rebuilt widened BMW calipers I have up front. I haven't bled them for at least 3 years now, so I'm overdue. The added necessity of finding someone to sit in the car and pump the pedal when I bleed the rear ones has made me keep putting it off.
Keep the valve at "wide open" to make it easier for the brake fluid (and air) to flow through while bleeding.Here is where I fitted the proportioning valve....
The question is, to bleed the brakes I need the proportioning valve in the minimum, maximun, does not matter?
Thanks, I'll try my best. Just waiting couple spares from germany to finish the project.P.S. When I had someone pump the pedal, I'm pretty sure I also still had my Power Bleeder hooked up. This didn't seem to cause a problem.
What happened is that after flare the pipe that connected the proportioning valve, I saw that it did not seal well. The threads in both places, "in and out", did not reach the end. Probably designed for a 3/8 x 1mm pitch connector with a longer end than the standard ones in EU and US. So I had to tap the proportioning valve... I think asian countries, like Japan and China have different standard in some kind of things... They are selling adaptors but the cost is higher than a new proportioning valve. BTW I couldn't find these adaptors in Europe, and once again, buying abroad is more expensive the ship and the customs fees than the item...Would you please elaborate on this? What happened here?
