Shimano BR-MT520 Disc Brake Caliper (Front & Rear)
What Is It?
The Shimano BR-MT520 F/R is a high-performance 4-piston hydraulic disc brake caliper set designed for mountain bikes and aggressive riding conditions.
It is part of Shimano’s Deore-level braking range and is built for strong braking power, heat control, and stable modulation on steep or technical terrain. It is commonly paired with Shimano Deore or compatible hydraulic levers using Shimano mineral oil systems.
This caliper is used for both front and rear wheels (F&R), often in full sets for complete brake upgrades.
