Default Brembo caliper alignment

Doing a brembo brake upgrade and noticed both rotors are almost up against (.005)the outboard caliper pad boss on both sides. I can pull the lower right slider out to centre the rotor but that will load the fork. Seems the only work around would be to machine (.040) off the caliper mounting boss to centre the rotors. Anybody come across this before?

I don't know if HD has shims. I know Performance Machine used to have a wide selection. I used them on a Pro Street FXR frame with Marzocchi legs. Good Luck.

Thanks for the tip! My calipers have to move towards the fork legs so shims at this point will not work.

They should fit without modification, what wheel are you using?

Stock wheel, 11.8 rotors. Yup, seems strange that it would be the same on both sides, the wheel can't really move left or right.

I have an 06 FLHX and im currently in the middle of the 2010 18" wheel install, the wheel spacers make a difference. Once the axle is torqued and clamped down, the rotors should be centered with in the caliper. I originally had one spacer size off and it shifter the wheel about a 1/4" closer to the left fork...caliper wouldnt even go on. Just make sure the caliper pistons are slideing out evenly on both sides, see where that set the running position.GL

Has anyone checked their caliper alignment after this upgrade or just bolted them up? The reason I ask is because the wheel turns fine with normal pad drag......

I hear ya about the spacers, but even with no spacers on the axle the rotors are at the outboard side of both calipers. Inboard pistons out roughly .100, outboard pistons flush.

Streeter,

While I don't have the Brembo upgrade on my 07 street glide (yet), I did notice that the brakes dragged ever so gently when I installed a chrome version of the 09 street glide wheel. From what the dealership told me this was normal. As a sanity check, I carried a IR temp gauge with me for a while and checked the temp of the rotors and calipers a few times. What I noticed is the brakes never got above 100 degrees when I didn't use them. So I suspect what you are seeing is "normal".

I'm sure under hard braking the caliper or fork leg may distort somewhat and with only .005 between the pad boss and rotor, there may be contact. Be interesting to hear from others who have done this upgrade to see where your rotors are sitting in relation to the padd boss on the caliper.

Cheers
