Brake fit tolerance

Doing a build and just installed the brakes. Is this too close to the frame? Or do I need to add a spacer to have a bit more space? The cables are not secured in the brakes yet fyi, just put on and torqued.

thanks?!






And also I have not tightened down the headset yet just in case your were wondering I have not cut the tube yet.

I would have said you have too many spacers. Depending on the clearance, the pads should tuck inside the frame and forks., Yeas, that's a PITA but you'll bend the pivot bolt otherwise.

I thought it looked hokey too actually. the first metal part that is attached to the bike. Its the first metal disk that the brake mounts to, its molded into the carbon fiber.

the second ring is the spacer that came with the brakes that I needed to get it not rub the frame.

the third larger star looking nut is fixed to the brake caliper.

I installed 1 spacer to get that very tight gap from the frame. I was hoping to avoid putting in one more to push it further out.

IIRC I've set up brakes where pads will hit the frame or forks when it's all released, knowing that will never happen when the bike is running down the road. If that's the case here, I wouldn't be concerned.

Yep, reckon that's the case here . Fit the brakes without the extra spacers and pads, then fit the pads with the brakes roughly adjusted so they'll clear the frame. Part of the pads will be covered.

I have a bike like that. As long as you can get the wheel in and out, it's a complete non-issue.

thanks all. I will run it as is. If it becomes an issue I can just add a spacer. I just didn't want to put it in looks odd enough already.

thanks!

Just to be clear, I'm adding my vote to those saying you should remove the middle spacer. You don't need it, or any more!

Yep, when I do actually get it set up I will see if I can do without. I don't want it there unless I have to. It will be really close though.....

the fit inside the forks....they are pretty stout/thick forks so the clearance isn't as high as other bikes I have.

So, this is all hypothetical until you hook up the brakes and put in a wheel. But if for some strange reason there isn't enough room between the fork blades, your rim, and both pads, KoolStop makes a "Thinline" pad that frees up some room: Kool Stop International - High Performance Bicycle Brake Pads Since 1977
