I have the opportunity to buy some second hand Mono M4's and I'm wondering if they'll be suitable for my kind of riding. I have a '09 Trance X and I do xc and some fairly fast techy stuff too and I'm 12 stone. I'm not after downhiller brakes but something fairly powerful is needed. At the moment I'm just about getting by with my juicy 3's but they scare me sometimes.
I think the m4's might be about 3 or 4 years old so I'm wondering if they age well? What are they like to set up and maintain? What pads are good ones to get and what's the pad life like? Have you had any problems with these brakes? Any info greatly appreciated. Thanks.
