Worn calliper holder bush

[Guest]

Just stripped the front brake calliper on my GS1000. The calliper axel is badly worn and only a credit card will fix however the bush in the calliper holder is also larger than it should be. Has anyone managed to replace the bush and if so what size bush is required?

I have a pair of the 79 hockey-puck calipers that I'll never use.
I'll have a look at them for wear (I'm fairly sure they're ok) and if they're not knackered, you're welcome to them.
I replaced them with the 80-onwards calipers as they're simply much better, and the internal cavity of the 79 casting was a corrosion trap - so much so that I decided not to chance using them at all.

Grimly you’re a star. Was hoping to just put new bushes in however your suggestion sounds a lot easier. Drop us a PM if you think their ok and well come to an arrangement.

Thanks,
Greg

Personally I’m not sure why anyone would use that old caliper.... I’m with Grimly on that

Sure, the bores can be drilled and bushed. But be aware that a fair bit of "slop" is necessary for the brakes to work correctly; I don't know what this clearance is supposed to be, but if it's too tight the calipers can bind.

As noted above, if you actually ride the bike, it's going to be best to put the money and effort toward updated calipers unless there's some compelling reason to keep the bike 100% original.
