The RCB (Racing Boy) E-Series Front Brake Pads are premium, aftermarket semi-metallic brake pads designed to deliver reliable stopping power, consistent lever feedback, and excellent value. Engineered with street-focused friction material, the E-Series balances an aggressive initial “bite” with long service life, making it a popular replacement for everyday commuting and spirited weekend touring.
This specific front brake pad configuration fits perfectly into the factory Nissin front calipers of both the Honda CBR150R (all modern generations) and the Honda CB150X adventure-touring motorcycle.
Key Features
-
Semi-Metallic Friction Blend: Offers a strong, progressive braking coefficient that works predictably across both cold morning starts and hot, high-speed applications.
-
Disc-Friendly Formulation: Engineered to minimize rotor abrasion, preventing premature grooving or wearing out of your front brake disc.
-
Weather-Resistant Traction: Specifically treated to function effectively in both dry and wet conditions, ensuring rain or mud doesn’t cause sudden drop-offs in braking force.
-
Advanced Heat Dissipation: The backing plate is coated with anti-corrosion and thermal-resistant paint to insulate brake fluid against boiling under continuous braking down steep declines or in city traffic.
-
Low Dust & Quiet Operation: Formulated to reduce dark brake dust on your alloy wheels while preventing high-pitch squeals during gradual deceleration.
-
OEM Standard Geometry: Built through a precise manufacturing process to exact factory specs—retains standard pin alignment for an immediate, hassle-free swap.

Maintenance & Bedding-In (Run-In) Guide
-
Clean the Rotor: Before sliding the new pads into the caliper, spray the brake disc thoroughly with a dedicated brake cleaner to remove any residual glaze, grease, or old pad material.
-
Check Fluid Level: Pushing the caliper pistons back in to make room for new, thick pads will cause the brake fluid level in your master cylinder reservoir to rise. Ensure it does not overflow.
-
The Bedding-In Process: Brand new brake pads require a short “bed-in” period to match the micro-grooves of the rotor. For the first 50 to 100 km, avoid sudden, panic-style hard braking. Instead, execute gradual, moderate slowdowns from 60 km/h to 10 km/h to safely transfer a uniform layer of friction material onto the disc.
