Front Brake Caliper Adjuster Question
« on: November 13, 2011, 08:43:59 AM »
I would like to get some opinions on whether or not it is necessary to keep the caliper adjustment screws on my 75 CB550.  I have looked through the posts and see that many people remove the adjustment screw with the spring. First some background...I just finished converting to dual disks and can't seem to get the brakes aligned properly. I replaced the pads with new EBC's, new gaskets, phenolic piston on one side and a stainless on the other (I already had it), new ss lines, speed bleeders, ground rotors and still running the stock MC (per Two Tired's advice).

The pads and calipers appear parallel to the rotors but I still get a high pitched squeal when I ride (it stops when I apply the brakes). I have only ridden the bike about 10 miles since the conversion and know that the pads need to bed in. I also notice that the new caliper adjuster has to be barely threaded for the caliper to run parallel. Would removing the adjuster make a difference or am I missing something else?

I did see the heated post about adjustment screws started back in March but it didn't really answer my specific question.

Thanks in advance.

If you remove the adjuster, the A pad will continue to withdraw into the caliper from road bumps and such. After an extended period of riding you won't know how far the A pad has withdrawn. Then when you go to grab some brake you will have to squeeze the lever into the grip much further, maybe all the way, and then double pump the lever to finally get some brake.

This is a safety issue and i would highly recommend that you leave the adjuster screws in place and properly adjust them. The amount of the gap, provided by proper adjustment, about 6 thou i think, is all that you should have to overcome with lever travel, before you get braking force.
