YOXUFA Rear Brake Master Cylinder Kit for 90–250cc ATVs and Pit Bikes — 70" Braided Line, Universal Fit

This all-in-one replacement kit bundles a rear master cylinder with reservoir hose, a 70-inch braided brake line, mounting bolts and cable ties so you can restore or improve rear braking on Arctic Cat, Suzuki, Chinese-brand ATVs, Yerf Dog, Helix, Coleman carts and many 90–250cc dirt bikes. The components are offered in commonly used lengths and include a threaded rod and pre-specified hole spacing to simplify fitment and reduce modification time.

Will this master cylinder fit my 90–250cc ATV or pit bike?

The YOXUFA unit is built as a universal replacement and can be modified for many small-displacement bikes and carts. Verify the listed dimensions against your machine’s mounting points and cable routing before purchasing.

• Total assembly length: 190 mm (7.48 in)
• Mounting hole spacing: 45 mm (1.77 in)
• Threaded rod length: 66 mm (2.59 in)
• Oil tube: 292 mm (11.49 in); braided brake hose: 1778 mm (70 in)

How does the kit improve installation or maintenance?

This package includes everything needed to install a rear brake control: master cylinder with reservoir hose, a long braided line for flexible routing, two bolts for secure mounting and ties to fasten lines. Using a braided line reduces hose expansion under load, giving crisper pedal feel compared with older rubber hoses.

• Includes one master cylinder and one 70" braided brake line
• Two mounting bolts and six cable ties for neat routing
• Pre-measured parts cut down on trimming and guesswork
• Braided line resists swelling for firmer braking response

What should I check before ordering or installing?

Confirm your vehicle’s mounting hole distance and available hose routing space. Also compare the threaded rod engagement and reservoir hose length with your existing hardware to avoid clearance or pedal-travel issues once fitted.

• Compare the 45 mm hole spacing to your brake lever bracket
• Ensure 70" braided line reaches caliper routing path
• Check threaded rod length (66 mm) for clevis or pedal fit
• Verify reservoir hose and oil tube lengths match your layout

Who this is for: Mechanics, hobbyists and owners of small ATVs, pit bikes, go-karts and compact utility buggies who need a direct replacement or an upgradeable rear brake assembly. It's suited to those comfortable measuring mounting points and adapting universal parts when exact OEM spares are unavailable. If you want a ready-made kit with ample hose length and a braided line for firmer response — and you can confirm the listed dimensions fit your machine — this YOXUFA kit is a practical, cost-effective option.
