"You'd be hard pressed to find another hydraulic brake out there that offers this level of performance and reliability at such a reasonable price."
Shimano's Deore hydraulic brakes are a prime example of technology trickling down to a more wallet-friendly pricepoint. For less than $120 per wheel, you get Shimano's proven mineral oil powered hydraulic brake technology, including the compact lever shape that's one of the best designs around. There's no tool-free reach adjust, and the cooling fins found on the pads of Shimano's higher end models may not be present, but those are small things compared to how well the brakes work, and feel. There's enough power on tap for all but the burliest of downhills, and if you do ever need to bleed them, it's a quick, hassle-free procedure. You'd be hard pressed to find another hydraulic brake out there that offers this level of performance and reliability at such a reasonable price.
Shimano’s latest Deore brake offers all the control and power you could need in a simple, ultra reliable, user friendly, ultra bargain package.
Whenever we asked for feedback on these brakes, the unanimous answer was that they were absolutely outstanding.
The calliper is a bit basic – with its fixed hose exit creating a big cable loop on some bikes – and it’s not a light system either, but the stock organic pads last okay and sintered sets improve dirty weather durability extensively, as well as behaving better in hard and hot use situations.
The lever end is neatly workmanlike, with Shimano’s double-decker master cylinder and one-and-a-half-finger lever giving good feel. The hinged I-Spec mount means it syncs well with shifters/remotes. You can adjust the reach with an Allen key, and the funnel based bleed system is user friendly.
The cunning ServoWave cam moves the pads on to the rotor quickly and then increases power at the point of contact. The consistent modulation and control were praised by everyone who’s used the Deores. Rub-free calliper set-up is easy and reliability is fantastic.
The M615 is outstanding value, whether you only need the brake or the reasonably priced rotor and mount too. Check the numbers though – older Deore M575 brakes are wooden, glaze-prone and still lurking under some shop counters.
