Shimano BR-MT520-BL-MT501 4-Piston Brake
There is only one thing better than a dual piston Shimano brake and that is a 4 piston Shimano brake. Despite its 4-piston design, the BR-MT520 brake caliper has almost the same slim design as those with dual pistons. The pistons are insulated for improved heat management and control of brake pad wear. The four-piston design also increases modulation, allowing for a more predictable application of braking force. These are a very capable brake, suited to a wide range of conditions and riding styles. Paired with the updated BL-MT501 lever with servo wave technology makes these a great value option for the price.

Some Assembly Required
by Loren Beaber
My set came as assembly required. Parts (minus fluid) were all there but not connected. If I had known this I would have ordered fluid. Otherwise quality and service were to a high standard.
Got these to replace some low end Shimano 2 pots on my Cube. Obviously the available power is a lot more but the modulation is much better so less likely to lock up a wheel unexpectedly. I like the minimalist look and actually prefer to use an allen key for reach adj. instead of some knob that can get smashed off, on that note the bite point moves out as you adjust the reach out and most things I have read people mention the separate bite point adjust on Shimano levers is next to useless anyway. Finally if this helps anyone, for my rear brake which is internally routed I didn't really want the hassle of swapping out my existing BH-59 for supposedly " Hi power " BH-90 hose supplied with the brakes so just trimmed the lever end replaced insert and olive (olives are same for both hoses) and bled, all good, Great value product if you don't need flashy looks and branding and just want something that actually just works properly !!
WOW - Do you need anything more than this
Bought for my street trials bike as I wanted a powerful set of brakes. For context the best I had used was Shimano xt (single piston) and am comparing against these. The MT 520's are way more powerful for a similar price and made a big difference in my confidence on techy moves. On the downside I can no longer blame the brakes when I end up on my A!#$.
I am not sure how they compare to the Shimano Zee's or Saint's but value of these brakes is outstanding.

Been putting my life in the hands of the hamsters that have been mauling my rather stock brakes that came with my Merida and with all the complaining they have been doing it has been rewarding to say the least to have traded them for a much quieter bunch...These fellas are much better behaved and say they are up to the task...
So far, none of the little guys have slacked off and can say your breeding program is definitely up to scratch...
