If your brake caliper uses Hayes HFX 9, HFX Mag, or MX-1 pads, these will fit.

Gorilla Brakes Semi-Metallic Disc Brake Pads are designed to restore smooth, predictable braking to classic Hayes HFX and MX-1 brake systems. Using a soft semi-metallic compound, these pads deliver quiet operation, fast bedding-in, and rotor-friendly performance for trail riding, recreational MTB, and everyday use.

🔧 Compatibility

Direct replacement pads for the following Hayes brake systems:

Pad Type Brake Series Caliper Model Riding Discipline
Hayes HFX / MX-1 pad format Hayes HFX 9 Trail, Recreational MTB
Hayes HFX / MX-1 pad format Hayes HFX Mag Trail, Recreational MTB
Hayes HFX / MX-1 pad format Hayes MX-1 Trail, Recreational MTB

Not compatible with Hayes Stroker, Dominion, Sole, or newer MX series (MX-2, MX-3, MX-5).

🔥 Compound: Semi-Metallic

This semi-metallic compound is tuned for low noise, smooth modulation, and dependable braking. It beds in quickly, produces less rotor wear than full metallic pads, and performs consistently in dry and mixed conditions — ideal for older hydraulic systems.

Quick bedding-in Consistent performance after short setup
Rotor-friendly behaviour Reduced rotor wear on older systems
Stable modulation Predictable control on trail and mixed terrain
REACH-compliant compound Safe and compliant for UK & EU use
