TOOPRE Mechanical Line Pull Disc Brake Caliper, Aluminum Die-Cast Bicycle Brake Clamp, Front / Rear Options single piston

The TOOPRE Mechanical Line Pull Disc Brake Caliper is designed for riders looking for a durable and practical braking upgrade for bicycles and similar compatible applications. Made from high-strength die-cast aluminum with a powder-coated surface, this brake caliper is built for solid structure, corrosion resistance, and everyday reliability.

According to the product images and provided information, this model features a one-piece reinforced design, an extended drive arm, and fine adjustment structure for more convenient setup and brake feel tuning. The caliper is shown with a large rectangular pad opening that allows easier brake pad replacement, while the contact area design helps promote more even friction between the disc and pad.

This product is offered in front and rear specifications. The front version is marked F160 / R140, while the rear version is marked F180 / R160. Product images also show compatibility references for PM (direct mount / straight-mounted) and IS (side-mounted) installation scenarios, along with a 44mm installation hole center distance and 160mm standard 6-bolt disc reference. Weight shown in the images is approximately 213.19g for the front brake and 218.31g for the rear brake, which aligns with the provided weight range of about 215g each.

Product Features

The product images highlight several practical construction details. The caliper uses a reinforced one-piece structure intended to provide stable braking support. An inner steel / outer plastic bushing structure is shown for fine rotational adjustment, while the threaded hardware and 10.9-grade screws are described as tightly assembled for stable use.

A push screw adjustment design is also shown, allowing the brake pad to move closer to the disc as the pad wears over time, helping shorten brake stroke and maintain braking feel. In addition, the vertical locking pin and common brake pad specification design shown in the images make replacement and maintenance more convenient.
