Problems with disc brakes after they are a few rides old, is the most common mechanical problem on MTBs. They are just so unreliable (And heavy) The only set that were ever any good, were the original Hope C2's that were a closed system.
My only advice is to stick with either Canti's or V brakes, lighter, easier to set up, reliable and it teaches you to ride a line properly and keep off the brakes.
Most race frames still come fitted with V brake bosses for this reason and why between 25 and 50 percent of most starters at Mtb races steer well clear of discs. Drag is a real problem and has never really been addressed by any of the manufacturers succussfully.
Hope this helps?
How does that textbook retrogrouching help? Clearly you've never ridden a decent disc brake if a crusty old C2 is 'the only set that were ever good'!
Unless this post has magically come across the web from 2001, you need to update your experience a bit before you start dispensing advice.
Anyway, it would be really helpful if we could know what brake the issue is with. I'm going to predict its an Avid, which have significant issues with the pistons seizing due to rubbish sealing and poor tolerances. If not, we'll work it out.
Had just about everything, right up to present day, and they are all as bad, it's the modern open systems that are the problem, no vaccum from the lever to pull the pistons back in and grunge finds it's way inside very soon and they drag.
Avids are rated as one of the better, but are still very poor. I would say Shimano are the most reliable, but piston retraction is still an issue, with the dreaded rotor drag.
All the bikes I service and the No 1 fault i with modern Mtb's is Disc brake drag. We also get a lot more Mud and rain here than most other countries! BTW
Also He clearly states Tektro front and Hayes Stroker rear, no mention of Avids at all.
Live the dream-Ride on!
