1990 Fire Mountain - Rear Brake Assembly.

[TimEC]

I'm hoping somebody might be able to dig me out of a hole?

Managed to get a 1990 Fire Mountain up together, having salvaged it from a terrible fate. It's almost servicable now.

Much of the bike was in pieces and I've had problems sorting out the rear brake. It's a cantilever/u brake set-up and I've not seen another. Think it was Shimano 500LX? I'm not sure I've got it back together correctly, but think I'm only missing the self centreing springs - these don't look to have been very standard?

Can anybody confirm? Also, any advice on sourcing them gratefully received.

I'm working to a deadline. Family are off to Centreparc, and I'm getting it in the ear because I possess three bikes and none of them are actually rideable...which is a fair gripe - them cluttering up the house and not earning their keep - a bit like me.

Post a pic so we can identify better, but U-brake was Exage 500 LX U-II one (silver). I cannot help you though

Hopefully, he's going to do the business and give me an answer too, which will be very nice of him.

Dunno about self-centre-ing springs, I don't think my Fire Mountains have any. As far as I'm aware the spring is captive in the brake assembly. The only adjustment I can think of is the eccentric lobe that the brake booster fits on to and the small grub screw, which adjusts spring tension.

Music to my ears...

I'm not missing anything - other than brains - I must admit, fiddling around with it there seems to be few reasons why it shouldn't work. I'd assumed there should be some because of the tiny holes to attach them to in the frame.

Thanks.

U-brakes can be weird. If it won't centre, or if one side feels like it has no tension, take the fixing bolt out and put it back again.
