Mikec Posted August 3, 2013 Report Share Posted August 3, 2013 Hi guys, I've just picked up a bike, its got, I think, an hs33 rear brake, I've just had a go in the garden and it seems a bit spongy, its got a lot of travel too. If I stand on one crank the brake struggles to stop the wheel turning. I've never used mags, but this doesn't seem right, I'm guessing it might need bleeding? I realise it isn't easy diagnosing over the net, but any help much appreciated. Cheers mike Quote Link to comment Share on other sites More sharing options...
dngr2self Posted August 3, 2013 Report Share Posted August 3, 2013 I'd start by bleeding it and go from there. It most likely will be that though. Quote Link to comment Share on other sites More sharing options...
Mikec Posted August 3, 2013 Author Report Share Posted August 3, 2013 Ok also noticed its flexing the rear stays too as there's no booster, so that won't be helping either Ill get on google now and watch some videos. Cheers mike Quote Link to comment Share on other sites More sharing options...
*gentlydoesit Posted August 3, 2013 Report Share Posted August 3, 2013 How far are the pads from the rim in the brake off position? I had that problem with mine. I moved the slaves in a bit and if was much better, though a bleed is always good Quote Link to comment Share on other sites More sharing options...
Mikec Posted August 3, 2013 Author Report Share Posted August 3, 2013 Just read up on here, did the bath bleed with water, first time and there sound as a pound now, just need to adjust the pads so there square with the rim. ( I hated doing this with v's :0. ) Cheers againOh, the tpa screw doesn't really turn, I've read people saying when selling the mag brakes, "tpa works" or similar, so is this what happens when they don't work? Doesn't really matter either way as long as the brakes work, just out of interest? Cheers Quote Link to comment Share on other sites More sharing options...
bing Posted August 3, 2013 Report Share Posted August 3, 2013 Yeah, it's so you can get the pads closer to the rim without undoing all the clamps, to adjust your bite point. Out of interest what's your setup? Frame/rim/04,05,2011 maggie/pads? Bang a photo up so the trials forum massive can dish out some help. If your frame is visibly flexing, then a booster, either 2 or 4 bolt might be a good investment Quote Link to comment Share on other sites More sharing options...
Mikec Posted August 3, 2013 Author Report Share Posted August 3, 2013 Cheers bing. That makes sense. I've only just bought it today and its my first trials bike so not sure on some stuff, but from what I can tell its an onza wheel, with a grind. It's a tpro, so I'd imagine its the origianal wheel?? It is a bit of nuisance setting the pads up though, a bit fiddly, like v brakes, I thought id done with all this when I got a disc mtb a few years ago :0 Ps not sure on the year I imagine its the early oneOh pps. Got sorted with a booster from someone on here so that'll help Quote Link to comment Share on other sites More sharing options...
bing Posted August 3, 2013 Report Share Posted August 3, 2013 (edited) Its an 09 t-pro that dude. The plastic tpas on those levers are shite unless they are brand new anyway. Good news is with a decent bleed they work quite well. Looks like onza lime pads, and deffo get a booster on that frame. Get some different pads though, cos they won't last 2 mins on a grind and they are a bit cack anyway. Plastic backed heatsink yellows or cousts for the win Edited August 3, 2013 by bing Quote Link to comment Share on other sites More sharing options...
Mikec Posted August 3, 2013 Author Report Share Posted August 3, 2013 I did a search on which pads to get but to be honest got a little lost with it all. Ill get some sorted. Cheers mike Quote Link to comment Share on other sites More sharing options...
bing Posted August 3, 2013 Report Share Posted August 3, 2013 Cousts Heatsink yellows Trialtech sports Any tnn's Try all croco yellows Rockman blue/green Any of the above will be decent for you with a nice fresh rim grind Quote Link to comment Share on other sites More sharing options...
Mikec Posted August 3, 2013 Author Report Share Posted August 3, 2013 Nice ill get some from tarty bikes cheers mike Quote Link to comment Share on other sites More sharing options...
williams Posted August 3, 2013 Report Share Posted August 3, 2013 Nice ill get some from tarty bikes cheers mike I'd recommend you to get any of the CNC backed pads. My favourite pads are Rockman CNC blues. TNN ADM's are pretty good aswell. Quote Link to comment Share on other sites More sharing options...
