Replacement Brake Pad

WHEELTOP RA7800 / RA7800 Pro / RA7000 Metal-Resin Brake Pad

A genuine WHEELTOP replacement brake pad set for the RA7800, RA7800 Pro, and earlier RA7000 hydraulic disc brake calipers. Semi-metallic resin compound on an aluminum alloy heat-sink backing plate — built to fit the original caliper spec exactly.

Pad Compound

Semi-Metallic Resin Compound

Wheeltop RA7800 metal-resin brake pad pair with spring clip

This semi-metallic pad uses a specially formulated resin powder in the compound, giving it stronger wear resistance, a shorter bedding-in period, and sharp brake response — the trade-off is a slightly grabbier bite under hard braking. It's also a more eco-friendly formulation than standard semi-metallic pads.

Aluminum Alloy Backing Plate

Each pad is bonded to a finned aluminum alloy backing plate, which also serves as the heat sink described below.

Cooling Design

Heat Sink Fins — Rapid Cooling Design

Fins are cut into the backing plate on multiple sides, channeling airflow across the pad from several directions for better heat dissipation.

Why It Matters

This cross-flow design keeps the pad and caliper running cooler on long descents, helping stave off brake fade when they're working hardest.

Compatibility & Buyer Notes

Please review the following before purchasing to ensure correct fitment.

RA7800 / RA7800 Pro / RA7000 Calipers Only

This pad set is sized for the WHEELTOP RA7800 series — RA7800, RA7800 Pro, and the earlier RA7000 caliper. It is not compatible with other caliper models.

Push the Pistons Back Before Fitting

This brake system automatically compensates for pad wear — as the pads wear down, the caliper pistons gradually extend to maintain the correct gap between the rotor and the pad. Because of this self-adjusting design, the pistons must be pushed back into the caliper before installing new pads.

When to Replace

Replace the pads if brake fluid contaminates the pad surface during bleeding, or once the pad material has worn down to 0.5mm.

Are WHEELTOP RA7800/RA7800 Pro brake pads compatible with my disc brake system?

WHEELTOP RA7800/RA7800 Pro pads are metal-resin composite pads designed for hydraulic and mechanical disc brakes commonly found on modern road and gravel bikes. Verify your brake caliper model (Shimano, SRAM, TRP, etc.) on the product page to confirm fitment, as pad mounting systems vary by manufacturer.

How difficult is it to install WHEELTOP RA7800/RA7800 Pro brake pads?

Installation is straightforward and typically takes 5-10 minutes with basic tools—usually just a hex key to remove the pad retention pin or bolt. No special tools or technical knowledge required; detailed instructions are included with each set of WHEELTOP pads.

What makes WHEELTOP RA7800/RA7800 Pro pads different from standard brake pads?

These pads feature an aluminum heat sink to dissipate braking heat more effectively, plus a metal-resin compound that delivers consistent stopping power across varied conditions while reducing noise and extending rotor life compared to standard organic pads.

How long do WHEELTOP RA7800/RA7800 Pro pads last before replacement?

Pad lifespan depends on riding style and conditions, but the durable metal-resin blend typically provides 500–2,000+ miles of use. Monitor pad thickness regularly and replace when they reach minimum wear indicators to protect your rotors.

Are WHEELTOP RA7800/RA7800 Pro pads suitable for wet weather and all-season riding?

Yes—the metal-resin compound maintains strong braking performance in rain, mud, and wet conditions, making WHEELTOP RA7800/RA7800 Pro pads ideal for gravel, commuting, and adventure cycling year-round. The aluminum heat sink also helps manage moisture-related fade.

Do WHEELTOP RA7800/RA7800 Pro pads work with carbon fiber rotors?

WHEELTOP RA7800/RA7800 Pro pads are compatible with steel rotors and most standard rotors, but check compatibility if you use lightweight carbon fiber rotors, as some carbon designs require specific pad compounds. Review the product page or contact support to confirm fitment with your rotor type.

Where can I buy WHEELTOP RA7800/RA7800 Pro brake pads with warranty coverage?

WHEELTOP RA7800/RA7800 Pro pads are available on Aoeagle's eBay store, which offers worldwide shipping and full manufacturer warranty on all purchases. Visit our store today to secure your pads and upgrade your braking performance.
