64cm bridgestone rear brake fit issue

[Guacamole]

Building a college commuter bike for my 6'6" son. I bought some used Shimano 105 brakes. It’s a Bridgestone 400 frame from the early 90s. The front brake fits perfect after a wee bit of drilling the backside of the fork.
The back wheel however is a bit out of a reach for the pads. Another 1\8th of an inch and they'll be there. Does anyone know of any tricks to make the pads reach the entire rim wall? 3\4s of the pads touch the rim but the last little bit almost touches the tire which is of course not safe and unacceptable. I much prefer to keep these newer brakes and make it work. Is there some sort of pads that has a lower pad and higher bolt to make the pad go a bit lower? Or some way to make this work? I just as soon not call a machinist friend to drill a flat piece of TI to lower the mounting. Ought to be an easier fix, yes? :confused:

Thanks

find a brake with more reach

file the bottom slot of the brake arm

thinking about the file job but hoped for something better...

This might be a longshot, but does the bike have horizontal dropouts? If so, is the wheel toward the back of the slot? If so, slide it forward and maybe the brakes will reach. Like I said, this is probably a longshot.

Good luck,
Dave

p.s. The fact that the front brake works, but the rear doesn't is what seems odd here. If it isn't a dropout slot issue, then you probably should just get some longer reach brakes. Shimano and Tektro both make some nice ones that are pretty reasonably priced.

Your caliper probably has a reach of 49 mm which is not enough. Shimano makes a longer reach that I think goes up to about 57 mm. I'd try to find one of those; they are not very expensive.

I'm the same height and had the same issues with the same sized Bridgestone I was building for a winter training bike. I tried to make it work with some DA brakes that I had but in the end my lbs set me up with a pair of longer reach brakes for a decent price. Worked just fine without all the hassle of "making" it work.

Thanks for all the input, I'll let you all know what I did...

Tektro makes some good quality calipers with long reach (really long reach) which might be a good option.

Here is an example that would give you up to 73mm of reach:

Tried the Tekros but they were too long..OY! :crap:

[picstloup]

I have had luck with Tektro R538's. They are light too!

As others have said, you need a brake a 47-57mm reach.

But offset brake pad holders do exist. They came with a couple of brands of carbon wheels that had lowered brake tracks.

You can get them here:

You need a brake drop bolt or longer calipers. Here is a drop bolt....

Cool. I hope that works well for your application.

Back when I was looking I don't think these were available so I went with longer reach brakes. Though I really wanted to use my DA brakes at the time.
