rear canti mount damage / repair?

Hi -

I'm hoping I'm in the right forum. The rear canti brake mount on my 1991 1/2 Gary Fisher Hoo Koo e Koo is damaged (cracked), and I'm trying to figure out if it's worth getting repaired. For the time being, I took off the rear brakes and just ride it (commuting) with front brakes only.

I contacted a local builder and based on the attached pictures he thought it would run about $100, and that I'd have to strip the entire bike down and would lose paint in the area of the repair. He may well be dead on, but I wouldn't know otherwise so I thought I'd ask around. I'm the original owner so there's some sentimental attachment to the bike, but if it's going to be economically costly I may just consider letting it go. She's been a loyal ride ... sigh.

Any thoughts are appreciated.

You can get a repair kit from Problem Solvers (Quality Bike Products) for this. I have installed dozens over the years. Cut the stud off at the break, file the end flat, run a M6x1 tap through the hole and install the kit. Works fine and holds up.

thanks, sounds like it could be a good option. i would just be tapping the length of the existing hole (and wouldn't need to extend it), correct?

You need to tap all the way through the boss. A pilot drill is sometimes required. The bolt goes all the way through and needs as many good threads as possible.

I've done this repair a number of times with good results. Some of the key is to file down the boss's stub as flat as possible so the bolt on replacement stands square and has no rock. Once I did have to file down the canti arm to prevent binding. Andy.
