When you're choosing bicycle drivetrain brakes, the main fork is hydraulic disc versus caliper design. The four sets here cover a mountain-bike hydraulic brake system and three caliper-style options for road frames. Your frame's mounts, wheel size, and riding style will decide which one fits.
Quick Take
- The Shimano SLX BR-M7120/BL-M7100 is the only hydraulic disc brake set in this lineup, built around 4-piston calipers and post-mount hardware.
- The Bike Brake Set with C Calipers is a full kit with levers, cables, a multi-tool, and two pairs of pads.
- The Tektro R313 Dual Pivot Set gives you front and rear calipers in black.
- The 700C Aluminum Side Pull Pair is a matched front-and-rear set for 700C road bikes.

Product Notes
Shimano SLX BR-M7120 BL-M7100 4-Piston Ice-Tech Hydraulic Brake Front/Rear/ Set
This set pairs BL-M7100 levers with BR-M7120 4-piston post-mount calipers and is configured as left-front/right-rear. The description highlights one-way bleeding, I-Spec EV compatibility, and tool-free reach adjustment. Brake hoses are sized 900mm front and 1600mm rear. The main limitation is that a rotor is not included; the description lists SM-RT70 rotors in 140, 160, 180, or 203mm as available separately. Choose this set for a mountain bike with post-mount brakes if you want hydraulic stopping power and adjustable levers.
Bike Brake Set, Front & Rear C Caliper Brake Kit, Bike Brake Pads, C Shape Brake Caliper
This kit includes a pair of C-style calipers, front and rear cables, a pair of brake levers, a multi-tool, and two pairs of brake pads. The rear cable is 200cm and the front cable is 23.6 inches, so the cable lengths cover a full front-and-rear run. Handles are alloy, the material note says plastic, and it's described as fitting most children's bikes, road bikes, and mountain bikes. That broad compatibility makes it a convenient all-in-one starting point, though the plastic material and mixed-bike description mean it's not a specialized race component.
Tektro R313 Dual Pivot Caliper Brake Set Front and Rear
This black Tektro set includes both front and rear calipers, so you get a matched pair in one purchase. The dual pivot design is named in the title, and the model is Tektro R313. The set includes the brake set and caliper, but not levers or cables. The condition is listed as "new other (see details)," so the listing does not describe the item as simply new. If you already have road brake levers and need a front-and-rear caliper set, this is a direct fit.
1 PAIR 700C ROAD BIKE BICYCLE ALUMINUM SIDE PULL CALIPER BRAKE FRONT + REAR
This side pull pair comes as one front and one rear caliper in silver, made from aluminum and branded MITSTOCKS. It's described as new and sized for 700C road and racing bikes, with a reach range of 40-50mm and a 30mm pad-to-pad distance. The limitation is the narrow fitment: it's a 700C road pair, so other wheel sizes or frame types won't match. You'll also need to provide brake levers and cables, since only the calipers are included.
Final Recommendation
For a mountain bike with post-mount brakes and a desire for hydraulic four-piston stopping power, the Shimano SLX set is the one that offers 4-piston hydraulic braking, but remember the rotor is sold separately. If you want a single box with calipers, levers, cables, and pads, the C Caliper Brake Kit covers the full setup. If you're on a road bike and need a complete front-and-rear caliper pair without extra parts, the Tektro R313 is the direct match. And if your priority is the lowest listed price for a new 700C aluminum pair, the side pull caliper brakes get you front and rear brakes for less than the other options here.
