Took the youngest off to Beddgelert forrest for a bit of cycling. Noticed rear break was playing up. upon return took brake apart. Found that inner pad was down to metal, outer had circa 1 mm left. Inside rotor is proud by about 2mm, outer is flat against body of brake body. Moved wheel over by 2mm by adjusting axle as thought this may be problem, centre line of disc wasnt matching centre line of brake. However couple of questions: Will callipers adjust once put new pads in? How long would you expect pads to last? Bike only 6 months old, done circa 30 hours of off road . I know they have to stop a lot of mass ( not bike, me!) but seems that either I should feel better about speed due to being held back due to brake rubbing , or, do I need to feel bad as I need to replace brake? Finally have searched internet for couple of hours for pads but not sure I can find correct set. None of the usual sites turn up results. Brakes are Shimano Shimano Br-M486, pads B01s resin. Found site on e-bay called VW mark shop that claims to sell uk made pads. Has anyone used them? Pads they have are Deore but dont say they fit BR-M486.

I always used the proper Hayes ones for mine when I first got them but when chain reaction stop doing a decent price on the four bundle pack I started looking elsewhere. Have been using Superstar on my full suss and they have been ok bar one incident where one wouldnt stay in place so I just swapped them for another pair and so far so good. Have also tried Disco Brakes on my hard tail that doesnt get the same sort of abuse and again so far so good. I'm no expert but for winter riding you want semi metallic or sintered try these www.discobrakes.com/?s=0&t=0&c=14&p=100&

I've used VWmark on ebay twice now for replacement Formula pads by Fibrax (welsh made I believe too!) and they're as good as the original pads with slightly more meat on them.

Thanks for the info. Disc says resin pads only so can I use other types of pads or will they ruin the disc?

However couple of questions: Will callipers adjust once put new pads in? How long would you expect pads to last? Bike only 6 months old, done circa 30 hours of off road If they're like the Shimano brakes on my hardtail (not same model), once you have the new pads in the caliper, just slacken off the caliper mount bolts slightly so the caliper can move side to side (you may need to temporarily remove the plastic clips around the bolt heads if fitted). With the bolts loose, squeeze the brake lever hard and hold it while tightenting bolts again at the same time. Disc should now be centred in caliper and shouldn't rub. The resin pads that come with Shimano brakes are usually a pile of poo and last about 5 minutes. Sintered ones are best if you want them to last through the winter mud. You may find the link below helps which says you need B01S pads as a direct replacement. If you Google "B01S" a few people are selling including JE James. techdocs.shimano.com/media/techdocs/content/cycle/EV/bikecomponents/BR/EV-BR-M486-F-2883A_v1_m56577569830667244.pdf

Or Superstar Components - they might put too much material on them so you have to sand a bit off to fit them in but at least the pads and the springs are made to the correct size (had another nightmare of a morning trying to put in some brake pads from Discobrakes again in case you can't tell)

Went for sintered from Disco in end. Lost the will to live trying to use superstar website. Entered some sort of parallel universe of trying to create an account. Just about avoided the Ikea factor of "oh that looks cheap. Its not what I need but I'll buy it anyway" when I looked at cost to upgrade discs to larger diameter. Decided that bigger discs would just look a bit to bling at present. Think I'll spend the money on some paint to change the sadle colour from white.

Let us know what you think when they arrive. I know all i've done is slag off the disco ones but i think i've just had a bad batch, the actual braking performance is fine and they're lasting well (once i managed to get them in ;D )

Brake pads arrived today! Only ordered Saturday night. Look like have lots of pad. Fitted in first time. No problem at all. Had to take brakes apart as one piston jammed. So now need to get some fluid. Given price of fluid can you use car power steering fluid which looks and feels the same? Have nice bick bottle of GM fluid.

Umm I don't think you can and I wouldn't want to risk it with something critical like brakes Brake fluid gets hot when you brake (as on cars) and the DOT4 or DOT5 refers to how hot it can get before it boils (and your brakes stop working). I wouldn't have thought power steering fluid would need to be designed for high temperatures even though they are both hydraulic systems.

Went to local bike shop and had to have smelling salts after learning how much they wanted for brake fluid. So went to halfords. They had no mineral oil only dot fluid for brakes. So guy then went out to workshop to show me oil they have been told to use for mineral brake systems. So you can buy 1L of halfords LHM plus specialist mineral fluid for circa £12. Probably enough to last several life times. On the basis that large chain is servicing bikes that take mineral oil for brakes with this fluid feel that liability alone for them probably suggests that this is OK. If I am wrong will let you know via Doris Stopes, or her medium
