Rob/Mitch Posted December 26, 2008 Report Share Posted December 26, 2008 Hi, I've now built up my new Simtra frame only to find my rear brake has lost its bite and noise.On my pitbull frame my rear maggie was quite loud and would bite hard without a booster but now it is silent and dosn't hold at all?Any Ideas what this could be?Anyone else had a Simtra that could shine some light? Thanks Rob. Quote Link to comment Share on other sites More sharing options...

Skoze Posted December 26, 2008 Report Share Posted December 26, 2008 Simtra's are made from granite, i doubt it'll be flexing. Quote Link to comment Share on other sites More sharing options...
steve@banbury-trials Posted December 26, 2008 Report Share Posted December 26, 2008 (edited) as the brakes have been removed from your old frame they probably aren't set-up in a identical position as they were,so they need to bed them in to their new position on your simtra,just give it a few rides and it should get better.steve Edited December 26, 2008 by steve@banbury-trials Quote Link to comment Share on other sites More sharing options...
grant_hundley Posted December 26, 2008 Report Share Posted December 26, 2008 Set it up well and let it bed in. Try re-grinding too Quote Link to comment Share on other sites More sharing options...
Jamie_Trials Posted December 26, 2008 Report Share Posted December 26, 2008 (edited) Hi maybe your pads need some sandpaper did the job for me this morning as, i dismantled mine thinking my new frame would fit but no Maggy mount Edited December 26, 2008 by Jamie_Trials Quote Link to comment Share on other sites More sharing options...
Rob/Mitch Posted December 26, 2008 Author Report Share Posted December 26, 2008 Do you have a booster on your Simtra?? Tooooo much flex is probably why? It dosnt seem to be flexing, not that i can see anyway. If anything my pitbull flexed more!Maybe it is just a case of bedding the pads back in?Think I need to do a bit of trueing work with my rear wheel aswell, I think the wheel was dished over by the last owner to fit the pitbull.It seems to be limiting my adjustment on one side, the caliper is pushed right back in the mount.

Muel Posted December 26, 2008 Report Share Posted December 26, 2008 I've found that more flexible frames tend to be more bitey than stiffer ones, but you'll never get the pads set-up right straight away.Give it a fresh grind so it will wear the pads in quicker and wait for them to wear in.

Muel Posted December 27, 2008 Report Share Posted December 27, 2008 I've never ridden an Ashton, but I've spoken to Krisboats about it before, and I changed a T-Pro to a Zona Zip, which was a lot stiffer, and put my brothers brake from his T-Lite onto my Kot, which is slightly stiffer.But yes, I'd love a go on your mates Ashton.

Rob/Mitch Posted December 28, 2008 Author Report Share Posted December 28, 2008 Had my first proper ride today on the Simtra, it feels so much better than my '05 Pitbull frame did, really nice on the back wheel. Going to try a steeper stem and go back to my risers and see how i get on. The front seems a little low and flat (if you know what i mean)The back brake is a little better but have been using tar all day, il give it a few more rides before i re-grind the rim i think.Cheers for all your help GuysRob.
