Rear brake for Gazelle

I'm trying to figure out a rear brake for my Gazelle Champion Mondial. The reason that I'm a little confused is that the fork is obviously drill for a recessed brake nut but the rear butterfly brake bridge will not accommodate a recessed nut.

Does anyone know what the original rear brake would have been? Any suggestions? Would drilling out the rear brake bridge be galactically stupid?

Here's a pick of the bridge...

I don't know what the original might have been, but why not just install a brake with a nutted center bolt? I would do that before drilling the bridge to accept a recessed center bolt. I don't think there's a rule which says that front and rear brakes have to be attached by precisely the same means.

Yeah, I was just hoping to install matching brakes both front and rear. I have a 2 full Shimano 600 groups in the parts bin and both have brakes with recessed nuts. I may just have to use brakes that don't match the rest of the group. Not a big deal but it sure would have been nice (and less expensive) to use matching brakes.

Since you have two full sets, can you use the other front brake on the rear and attach with a nut and washer? I did that on one of my bikes, works well.

I had no issue using a recessed nut on my AA frame. Same bridge.

If you can drill the brake bridge there should be no issue. The problem is getting a drill+motor behind the seat tube.

What year is that? Just curious. My '86 takes recessed brakes, but its rear bridge is different. Maybe your fork isn't original to the frame. Whatever...I say just use whatever fits. Don't try drilling.

I'm pretty sure Shimano 600 was available with nutted center bolt. You can find one such brake, swap the center bolts, and, presto! You've got recessed front, nutted rear, which look otherwise like a matched pair.

I wouldn't be surprised if the center bolt was common across several different levels of Shimano brakes.

Edit: Heck, I might have something. I'll take a look.

That is the best idea I've heard yet. You guys on the forum never let me down.

I'm fairly certain that the fork is original but since I'm not the original owner, I can't be 100%. The half an ounce of common sense that I have was telling me not to drill this frame. Most of the feedback on this thread confirms that I shouldn't do that. I'm still hoping that someone who is more of a subject matter expert on Gazelles will know what the original brakes were and chime in.

I'm not an expert but I found a few appearant experts who made a website:

http://jvs.webklik.nl/page/modellen

The listing of the used fittings seems quite thorough to me. Also the brochures in pdf have detailed pictures of parts some might recognize. Just let me know if I need to translate something for you.

My 1986 Trek 400 Elance came with a recessed front brake and a nutted rear. However the rear went into a "block" brazed onto the brake bridge- so it made it necessary to have a longer brake bolt. You could have just used a normal recessed brake bolt and nut, but the block wasn't drilled for it.


The brakes that came on it were some Shimano brakes that weren't high end, but they were nice enough mid-reach brakes.


I opted to install two front 600 tri-color calipers, dual pivot in the front, single pivot in the rear. I think they look cool that way.

Alas, I have two orphan nutted fronts, no nutted rear. Try posting in the ISO and For Trade thread part 4 thread. Someone will have what you need.
