Hey nice rack! -Celette Group: Members Posts: 20,681 Joined: 30-December 02 From: Now in Superior WI Member No.: 43 Region Association: Northstar Region |
I installed 4 pistons front calipers and a 19mm master cylinder this weekend. Also removed the "P" valve for the rear calipers and installed a "T" fitting. So the lines were pretty much empty. I added ATE Super Blue fluid and bled the system until I used a quart of fluid. After a day of hunting I managed to locate a friend that had a new quart on the shelf. We continued to bleed the system and added another half quart.
Here's the my issue... After bleeding the system for several hours I still have a low peddle. After the second pump of the peddle the hieght seems good. ( goes from 2/3 sweep to about almost 1/2) Do you think I need to continue to bleed the system or are the 4 piston calipers requiring the extra motion just to fill? Anyone running 4 piston calipers with a 19mm master cylinder? If so how much peddle travel do you have? |

Venting Clearance, Venting Clearance. Did you check it? And use 1/2 of the book spec?
Is the piston area more than the 320i calipers? If so, your rears may be undersized. Consider puting the stock fronts on the rear and installing an APV. Who uses a parking brake anyway? |
