Budget disc brakes
I'm currently running Shimano M615 disc brakes that've developed a horrible squeal. Before you ask I have tried new discs, pads, deglazing and degreasing both and obviously bedding them in. All of which temporarily stops the squeal only for it to return.
I fear that the calipers have developed leaks which are causing the squeal.
So what would people recommend as a budget (as cheap as possible) alternative?
I've currently got avid bb7 and magura mt2 in mind.
Ta.

I've got a pair of TRP Spykes for sale. Used but still fully functional. I'll throw in some Avid brake levers, cables and some sintered pads too. £100 the lot, posted.
Re: Budget disc brakes
CRC have some deore disc brakes for sale for £24 per end at the moment, got a pair last week, had to swap the hoses over but work great out the box without needing bled.

Re: Budget disc brakes
If they are leaking, you'll see oil running out of the caliper. leaks shouldn't cause squeaks, just make the brake not work. Check your calliper and calliper mount on frame alignment.
If you do go for new ones deores are great but if your calliper mounts are miss-aligned they will still squeal.... Pads wise use sintered ones but don't try Clarks el cheapo ones - squeal central!

Re: Budget disc brakes
Cheap Shimano calipers can develop micro leaks at the pistons (especially if laid up for a time) which contaminate the disc / pads yet don't effect lever feel or leak enough for oil to drip or really build up to noticeable levels.If they are leaking, you'll see oil running out of the caliper. leaks shouldn't cause squeaks, just make the brake not work.

Re: Budget disc brakes
Thanks, but that's more than the cost of either of the ones I mentioned.quimarche wrote:I've got a pair of TRP Spykes for sale. Used but still fully functional. I'll throw in some Avid brake levers, cables and some sintered pads too. £100 the lot, posted.

Thanks, that's good to know. I guess these are the ones: http://www.chainreactioncycles.com/mobi ... prod174433Taylor wrote:CRC have some deore disc brakes for sale for £24 per end at the moment, got a pair last week, had to swap the hoses over but work great out the box without needing bled.
Very similar to what I'm currently using, so I'm a bit concerned that they'll develop the same problem.

It could be calliper alignment, but i've already had fork bosses faced by LBS which hasn't sorted it unfortunately.htrider wrote:If they are leaking, you'll see oil running out of the caliper. leaks shouldn't cause squeaks, just make the brake not work.

Maybe I just need a new bike!

If they don't solve the squeal it'll have to be a new bike I'm afraid.
Re: Budget disc brakes
Shimano have had leaky pistons for years now, not just on there cheaper models but even my xt ones.
Magura mt5 are available for £65 an end at the moment.

Alpinetrek. But they appear to have cleared their stock now so none left.techno mail wrote:Where from?Nutsnut wrote:Shimano have had leaky pistons for years now, not just on there cheaper models but even my xt ones.

Re: Budget disc brakes
I've got no personal experience of them but the LBS were fitting a set of these to a customers bike and quite impressed with them, I think they might also have been recommended on STW recently

At £41.98 a pair including discs that's quite a bargain.
