Product Information

Full details

The Galfer Advanced Disc Brake Pads are engineered for trail, enduro, and e-MTB riders seeking a balanced performance upgrade over stock components. These organic-based pads provide consistent stopping power, excellent modulation, and impressive fade resistance, making them a reliable choice for technical singletrack and long descents; however, riders prioritizing absolute maximum power for competitive downhill racing may prefer the more aggressive Galfer Pro compound.

FAQs

Are these pads compatible with E-MTBs?

Yes, the Advanced compound is specifically recommended for e-MTBs due to its high heat resistance and consistent stopping power.

Do these pads work with stainless steel rotors?

Yes, they are compatible with most standard stainless steel rotors found on mountain bikes.

How do I know if the FD427 is the correct shape for my bike?

Check your existing brake caliper model number or the shape of your current pads. FD427 is a standard shape compatible with several common Shimano brake systems.

Should I sand my rotors before installing new pads?

It is highly recommended to clean the rotors thoroughly with isopropyl alcohol or a dedicated brake cleaner. Lightly sanding the rotor can remove old pad deposits, ensuring a fresh start for the new compound.

How long do these pads last?

Durability depends on riding style, terrain, and weather. The Advanced compound offers moderate to high durability suitable for most trail riders.

Troubleshooting

Braking feels spongy or weak after installation

Perform a proper bed-in procedure to seat the pads against the rotor surface.

Brakes are making a squealing noise

Check for rotor contamination. Clean rotors with a dedicated disc brake cleaner and verify the caliper is perfectly aligned with the rotor.

Pads wearing down very quickly

Ensure the brake caliper is not misaligned, causing the pad to drag. If riding in extremely abrasive, muddy conditions, consider the Galfer Pro compound for higher durability.

Pros and Cons

Pros

  • Excellent balance of power and modulation
  • Fade-resistant during long descents
  • Quiet operation across various weather conditions
  • Gentle on brake rotors to minimize wear
  • Ideal for the weight and speed demands of e-MTBs

Cons

  • Not as aggressive as the specialized 'Pro' compound
  • Organic blends may wear faster than full metallic pads in extreme mud
  • Requires a proper bed-in process for optimal performance

Setup, Compatibility & Care

The FD427 G1851 pads are designed for specific brake systems. Before installation, ensure your existing rotors are free from oil, grease, or previous brake pad debris, ideally cleaned with isopropyl alcohol.

  1. Remove the old pads and gently push the pistons back into the caliper using a plastic tool to avoid damage.
  2. Insert the new Galfer Advanced pads and secure the retaining pin or spring clip.
  3. Bed-in Procedure: Perform 20-30 controlled stops from a moderate speed on a flat surface to transfer a thin layer of pad material onto the rotor. Avoid full-force panic stops until the pads are fully bedded in.

Regularly check pad thickness; if the friction material is less than 0.5mm, replace the pads immediately to prevent metal-on-metal contact with the rotor.
