GREHUA Go-Kart Mechanical Disc Brake Caliper Kit — Steel Caliper & Bracket for Predator 212cc/GX160, Cable-Actuated, Reversible Ar

If you’re replacing a worn brake or retrofitting a pedal-style kart, this GREHUA kit offers a durable steel caliper, mounting bracket and hardware sized for popular small-engine go-karts like Manco 9597/9598, Yerf-Dog, Murray, ASW and Predator 212cc/196cc GX160 platforms. It’s built to accept rotors up to 1/4" thick and fits a range of pedal and cable configurations so you can get reliable, adjustable braking without complicated hydraulics.

How will this caliper improve my go-kart’s braking?

The GREHUA caliper converts cable pull into positive mechanical pressure on the rotor, delivering smoother, more controlled stops compared with worn drum systems or makeshift band brakes. Its compact steel body and side-mounted arm provide predictable lever action that can be repositioned for left- or right-side setups.

• Accepts rotors up to 1/4" thick for robust friction surface.
• Side brake arm is reversible for mounting flexibility.
• Cable-actuated design reduces maintenance vs. hydraulic units.

Will it fit my kart and engine combination?

Fitment covers many common chassis and engines—Manco models 9597/9598, Yerf-Dog, Murray, American Sportworks/ASW, Carter, Ken-bar, Bristers Thunder and Airheart MB-1. It also suits engines around the Predator 212cc/196cc and 6.5hp GX160 class, provided your mounting pattern and cable routing match.

• Mounting hole center-to-center: 5/7" (18.2mm).
• Mounting hole diameter: 2/7" (7.5mm) to accept supplied bolts.
• Brake arm length: 2" (50mm) for standard cable leverage.

How difficult is installation and what’s included?

Installation is straightforward for someone comfortable with basic kart maintenance. The kit is steel-built for longevity and uses a cable operating system that adapts to most pedal setups, with adjustability for different pedal positions to fine-tune engagement.

• Included: 1 caliper with pads, 1 bracket, 2 screws, 2 nuts.
• Cable-ready design — connects to pedal-style systems without hydraulic lines.
• Adjustable pad clearance for varying rotor thicknesses.

What should I check before buying?

Measure your existing mounting points and rotor thickness to confirm compatibility. Verify your cable routing and pedal geometry so the 2" brake arm delivers proper leverage and travel; minor bracket modifications can sometimes be required for unique frames.

• Confirm rotor max thickness of 1/4" fits your setup.
• Compare mounting hole spacing (18.2mm center-to-center) to your frame.
• Plan cable anchor and travel to ensure full pad engagement.

Who is this for? Enthusiasts and hobbyists upgrading or repairing small off-road and recreational go-karts—especially owners of Manco, Yerf-Dog, Murray, ASW and Predator-engine karts—will find this GREHUA mechanical disc caliper a practical, affordable option. It’s suited to riders wanting a reliable, low-maintenance cable brake replacement that’s simple to install and tunable for everyday track or backyard use.
