disc brake problem

liquidatorwolf said:

I recently bought a bike with shimano deore xt disc brakes. The problem is there is a real drag on the back wheel which doesn't spin freely. This is the first time i've owned a bike with disk brakes, and have been told this drag is normal while the pads burn in. Is this true, or do i need to adjust them. if I need to adjust them how do i do that ..

they shouldnt drag - you probably just need to adjust the cable and maybe the position of the caliper mounting bolts- go to the Shimano site and download the service instructions- it should be on there

cheers will look at shimano sight now

i recently got Hope Mono Mini's the back on tends to take longer to bed in than the front, just wait, it'll go away eventually, just look at the pads, if the disc is central to the pads it shld b fine

WHAT! NO FREE WHEEL MOTION? if u buy a new car with disc breaks the last thing you want is for the mo'fo' to drag! and even worse for some one to tell you that its ok and it will go away in time! [censored]! gettum' serviced or they might lock or grind your pad prematurely. its new it should work primo😄

thanks for the advice(s). I think the solution is to get it serviced the problems not going away

by the way try not to think of the brand as the lemon, like with any make or brand u get the occasional slip in the craftsmanship or a bump during shipping. although some people immediately switch brands, u can do so if it makes u feel better but chances are that if u take it to a good mechanic that does'nt seem to be in a rush or get another set the problem will be rectified. i have deore all around hubs, cassette, cranks, chain, derailers, discs; everything on a surly instigator with rs psylo f/ shock and i would totally reccommend the disc breaks and i'm 6'2" 285 lbs. which requires ALOT of stopping power. having discs means u probably have a nice bike and nice bikes should handle and feel nicely.🙂 good luck.

Disc brakes are adjusted by adding or removin very thin spacers between the frame and the caliper, look at the brake and you should clearly see that one pad is closer - adjust as needed.

If your a disc virgin you should be aware of a few things;
1. the fluid inside your XT could be hazardess to your self and will remove any paint it touches, so be carefull! This is a DOT fluid and has to be used in servicing.
2. You must clean the calliper, pads and disc with proper disc cleaner or fresh water, any cotamination will render the brake useless and new pads would be needed.
3. You have an open system which means are is alowed to enter the lever resivour, you may notice a small hole? If you allow the bike to be upside down for any period of time the air will travel into the hoses and towards the caliper, which will make the lever feel mushy and loose power, the system would probably need bleeding.

They will take time to bed in and the back will take longer than the front - when you brake try to make it last as long as possible to create more friction!

Enjoy!
