Azarathal Posted April 19, 2011 Report Share Posted April 19, 2011 (edited) Ok guys, going to be my last thread for a while, since moving to discs I feel like such a bikenewb again. Front disc, old style lever mono trials. The hope brakes I've felt seem to have very little lever travel, mine pulls in a bit further than I'd like and was wondering if I could fix this via bleeding? Rear disc, new style lever mono trials. #5 caliper with a +20 adapter so I can run a 160rotor on the rear. The rotor is too far to the left, and is close to rubbing. Without shaving any material off my frame / adapter I can't think of how to fix this? The right pad is quite far away and I'm guessing this is the reason why my lever pulls in quite far? Or is it just my shit bleed? After having my banjo bolt pop off and ruin new pads the other day, I've had to put new pads in and rebleed. I thought I'd done this perfectly, wrapped everything in tissue and had no visible spillage, now it seems both my front and rear discs are slightly contaminated, when they're wet they work flawlessly but as soon as they dry out they honk like a bitch, shall I just keep dragging the brakes + pouring water on them? Cheers for any help and sorry for the wall of text. Edited April 19, 2011 by Azarathal Quote Link to comment Share on other sites More sharing options...

A fresh bleed is always a good starting place if your brake feels a bit off. As for the second thing, no combination of washers will fix that, something needs to be modified. Mind you, if it doesn't rub, the old 'if it ain't broke don't fix it' springs to mind. Quote Link to comment Share on other sites More sharing options...

A fresh bleed is always a good starting place if your brake feels a bit off. Was bled recently, it's a good bleed it just pulls in slightly further than I'd like.

The right side pad is quite far away and the lever pulls in almost to the bar, I assume this is just a shit bleed though. Quote Link to comment Share on other sites More sharing options...

forteh Posted April 20, 2011 Report Share Posted April 20, 2011 The old mono trials are pretty flexy (well mine is) once its bitten you can then pull the lever to the bars, you can physically see the lever flexing and the caliper spreading. The new design are supposed to be much better. You cant fully adjust the bite point/lever travel on the old mini lever but you can adjust the lever reach via grub screw in the brass lever barrel, this does affect how the lever feels; if you wind it right in, it will bite sooner.

Azarathal Posted April 20, 2011 Author Report Share Posted April 20, 2011 Ok so I'll just leave my front brake alone. Ive watched the hope vids, I'm just wondering if it is a shit bleed or because one pad is so far away? Also, anyway to stop the honking front brake? Disc cleaner and drag it?

Ive watched the hope vids, I'm just wondering if it is a shit bleed or because one pad is so far away? Also, anyway to stop the honking front brake? Disc cleaner and drag it? The pads need to be equidistant from the disk and need to be hitting at the same time, if you have a sticky piston one may not move as freely as the other. If theyre both moving freely then you need to set it up properly, getting the disk mount faced can make a huge difference. Nick woods method of burning the pads off in a tin of meths seems pretty sensible, you need to properly degrease it to get rid of the oil, possibly leave the pads to soak in the meths for a little while. With the disk I just soak them in a shallow tray of solvent degreaser (cellulose thinners works well - couple of quid for a small bottle from wilkos, probably do the pads with it aswell), let it dry off and bung it in the oven for 20 mins at 150°c or so.

dirt jumper jake Posted April 20, 2011 Report Share Posted April 20, 2011 (edited) Have you got the tiny little hope shims? thats how ive sorted out my pads being odd distances from rotor. http://www.chainreactioncycles.com/Models.aspx?ModelID=356 "Range of stainless steel shims and washers used to fine tune your Brake Caliper spacing and centralise it on the disc. Poorly aligned brakes can cause brake pad rub and squeal." Edited April 20, 2011 by dirt jumper jake Quote Link to comment Share on other sites More sharing options...

AdamR28 Posted April 20, 2011 Report Share Posted April 20, 2011 You need to: Face the mounts on the frame. Bleed the brake - properly. Fit new pads and rotor that aren't contaminated (and haven't been contaminated in the past). Set it up correctly - rotor in the middle of the caliper.

EDIT: Sorry, in a bad mood, back to chit chat for me... The shop owner is such a stingy f**k, bike stands falling apart, useless wheeljig etc, I'm only there 'cos I choose my hours and get paid cash. Adam, I think I'm going to be ordering another set of pads :/ I cba with it anymore, I might just get cyclezone to do it while I've got cash to burn, once I've finished work I don't want to touch my own bike Quote Link to comment Share on other sites More sharing options...

Yeah that's fair play, just curious Seems odd that there is nobody there who can help though, could give Hope a ring for some tips? just wonering . why? I've only ever taken my bike to a shop for work once before, and never again. I have also worked in a few and know what most mechanics are like! I am sure there are good mechanics out there, but if you are able to do the work yourself then I don't see the reason to take it to a shop. I guess I should probably what I said above to 'I wouldn't trust any bike shop with my bike, apart from maybe a rear shock servicing, for which I would take them just the shock anyway ' Quote Link to comment Share on other sites More sharing options...
Azarathal Posted April 20, 2011 Author Report Share Posted April 20, 2011 My shop is stupidly underequiped and the owner has no business sense and no customer relations. The manager is alright though, a bit eccentric but he knows his stuff. Give hope a ring regarding what exact problem? Quote Link to comment Share on other sites More sharing options...
