BUCKLOS Hydraulic Disc Brake Set for MTB, Front+Rear Black, Pre-bled Mineral Oil, Dual-Piston

BUCKLOS MTB Hydraulic Disc Brake Set delivers high‑power, pre‑bled hydraulic stopping for mountain bikes with left-front 800mm and right-rear 1450mm hoses.

Designed as a bolt‑on upgrade for riders who want stronger, quieter braking than mechanical systems, this BUCKLOS kit pairs a dual‑piston caliper with resin‑metal pads, pre‑filled mineral oil lines, and a left‑front/right‑rear hose layout (800mm front, 1450mm rear). It supports 160mm rotors out of the box and can work with larger rotors when using the correct adapters. The package aims to fit a broad range of bikes—including e‑bikes, folding bikes, fat bikes, BMX, scooters and traditional mountain bikes—while keeping installation straightforward for home mechanics and bike shops.

How much stopping power will I get with these hydraulic brakes?

The BUCKLOS set uses a dual‑piston caliper and mineral‑oil hydraulic actuation, providing significantly stronger and more consistent braking force than typical mechanical disc systems. You can modulate braking with light lever pressure, making it easier to control speed on steep or technical terrain.

• Dual‑piston caliper for improved bite and even pad wear
• Resin‑metal composite pads for quiet, effective braking
• Pre‑bled mineral oil lines for immediate performance
• Compatible with 160mm rotors; adapters enable 180mm or 203mm

Will these brakes fit my bike and rotor sizes?

The set is engineered to fit most bicycles that accept hydraulic calipers, including electric bikes, fat bikes, folding bikes, BMX and scooters. It ships configured for a 160mm rotor; if your bike uses 180mm or 203mm rotors, you must swap in the correct adapter brackets for proper caliper alignment.

• Standard fit for 160mm rotor mounting
• Adapters required for 180mm or 203mm rotor upgrades
• Left‑front (800mm) and right‑rear (1450mm) hose layout matches common user preference
• Works with a wide range of frames and dropouts—verify hose routing and length before install

How easy is installation and maintenance for non‑professionals?

BUCKLOS supplies the brakes pre‑bled with mineral oil, so there's no initial bleeding required if you do a direct swap. Installation involves mounting the calipers and levers, routing hoses, and bolting on rotors or adapters as needed—basic bike mechanical skills and standard tools suffice for many riders.

• Pre‑bled mineral oil lines reduce setup time and mess
• Confirm hose length (800mm front, 1450mm rear) fits your frame before tightening
• Simple pad replacement and routine checks: rotor alignment, bolt torque, and fluid inspection
• If converting rotor size, replace adapters for correct spacing

What kind of noise, wear, and durability should I expect?

The resin‑metal composite pads are designed to reduce squeal and preserve rotor life compared with harder materials. With proper bedding, alignment, and routine inspection, the system runs quietly and resists premature rotor wear under normal trail and road conditions.

• Resin‑metal pads minimize braking noise and protect rotors
• Even pad wear thanks to dual‑piston caliper design
• Durable hydraulic lines pre‑filled with mineral oil for corrosion resistance
• Regular checks recommended after intensive downhill or wet use

Who is this for: The BUCKLOS MTB Hydraulic Disc Brake Set is made for riders upgrading from mechanical discs or entry‑level brakes who want stronger, quieter, and more controllable braking. It's well suited to trail riders, commuters, and owners of e‑bikes, fat bikes, folding bikes or scooters seeking an approachable hydraulic conversion. Confirm your frame’s hose routing and rotor size before purchase to ensure a smooth installation.
