Cycle1st Ceramic Brake Pads for 4-Piston Calipers, Silver, 1 Pair — Thermal Stability and Longer Life

Cycle1st ceramic brake pads for Shimano, Tektro and TRP 4-piston calipers are high-durability replacement pads engineered to deliver consistent stopping power and longer service life for e-bikes, eMTBs and aggressive trail bikes.

These replacement pads combine ceramic, aramid fiber and copper to produce a blend engineered for improved thermal stability and extended wear life compared with standard resin pads. Designed in Taiwan for riders using Surron and popular Shimano SLX/XT four-piston systems (plus compatible Tektro and TRP calipers), they are a direct-fit pair intended for demanding conditions such as long descents, heavy payloads and frequent braking on technical terrain.

How do these pads improve braking performance on heavy bikes and e-bikes?

The ceramic/aramid/copper compound resists heat buildup and maintains more consistent friction under repeated braking, reducing the rate of fade during long descents. That thermal stability helps the pads preserve bite and linear feel as temperatures rise.

• Automotive-grade materials for stable friction at elevated temperatures
• Reduced brake fade compared with standard resin pads
• Optimized for higher mass and torque from e-bikes and loaded rigs
• Consistent modulation for improved rider control on long descents

Will these pads fit my Shimano SLX/XT or Surron 4-piston calipers?

Cycle1st pads are shaped to match many four-piston calipers used on mountain and e-bike platforms, including common Shimano SLX and XT configurations as well as compatible Tektro and TRP models. Always cross-check the pad profile and mounting style against your caliper before ordering to ensure a correct fit.

• Compatible with Shimano SLX and XT four-piston setups
• Also fits many Tektro and TRP 4-piston caliper designs
• Check product images and descriptions for exact fit references
• Contact support with photos if you need fit confirmation

How long do these ceramic pads last and what maintenance is recommended?

These pads are designed to outlast typical OE resin pads—often lasting three to five times longer depending on terrain and rider style. Regular inspection for pad thickness and rotor condition will extend life and preserve braking performance.

• Expect significantly longer service life versus standard resin pads
• Inspect pad thickness before each ride and replace when worn
• Keep rotors clean and free of oil or debris for optimal contact
• Follow the included installation guide and break-in recommendations

What should I know about installation and initial setup?

New ceramic pads can be thicker than old, worn pads; caliper pistons must be fully retracted before installation. The packaging includes a QR code to view a step-by-step installation guide—cleaning pistons with isopropyl alcohol is recommended if pads seem difficult to seat.

• Retract caliper pistons fully before fitting new pads
• Clean caliper and pistons with rubbing alcohol for smooth retraction
• Follow the manufacturer’s QR-coded installation instructions for torque and pad alignment
• Perform a controlled bed-in process after installation for best results

Who is this for: Cyclists and e-bike riders who push hard on technical descents, carry extra load, or ride frequently and want a longer-lasting pad with stable braking under heat are the primary audience. These pads suit riders of cross-country, enduro and downhill disciplines, plus commuters or cargo riders upgrading heavier platforms like Surron and eMTBs. If you need dependable stopping power with extended service life and you ride a four-piston caliper system from Shimano, Tektro or TRP, these pads are engineered to meet those demands.
