NGage HB 238 / HBS 238 Rear Brake Pads for Yamaha R15 V3, V4, MT-15, FZ 25 & Fazer 250 – Ceramic & Sintered Options (Rear Only)
The NGage HB 238 and HBS 238 rear brake pads are precision-engineered disc brake pads designed for Yamaha motorcycles that use the HB 238 pad shape specification at the rear caliper. These brake pads are intended as direct-fit replacements for factory rear pads on compatible Yamaha models, delivering stable braking performance, controlled heat behavior, and consistent pedal feel across everyday street riding as well as spirited use.
Rear brake pads play a critical role in overall braking balance. While the front brake delivers the majority of stopping force, the rear brake stabilizes the chassis under braking, controls speed in low-traction conditions, and supports smooth deceleration in traffic, corners, and downhill riding. The NGage HB 238 and HBS 238 pads are built specifically for this rear-brake role, offering predictable bite, progressive engagement, and long-term durability.
These pads are manufactured to match the exact dimensions and mounting profile required for the Yamaha rear calipers used on the listed models. Fitment, seating depth, backing plate thickness, and friction block positioning are all controlled to ensure correct alignment with the disc rotor and caliper pistons. This allows the pads to install cleanly without modification and operate within the factory braking geometry.
Material Variants – Choose What Matches Your Riding Style
This listing is offered in two NGage material variants, both sharing the same pad shape and fitment:
HB 238 – Whisker Ceramic Brake Pads
The HB 238 uses a ceramic-based friction compound engineered for smooth, quiet braking and controlled wear characteristics. Ceramic pads are known for consistent modulation, low brake noise, and reduced rotor abrasion. This compound is well suited for riders who prioritize clean operation, stable braking feel, and predictable response in daily commuting and mixed riding conditions.
HBS 238 – Sintered Brake Pads
The HBS 238 uses a metallic sintered friction compound designed for higher thermal stability and stronger braking bite under heat load. Sintered pads are formed by fusing metal powders under pressure and heat, producing a dense structure that resists fade and maintains braking effectiveness during aggressive riding, highway use, and repeated braking cycles. This compound is ideal for riders who demand sharper response and higher durability under demanding conditions.
Both variants are identical in physical dimensions and mounting compatibility. The only difference lies in the friction material behavior and performance characteristics.
Performance Behavior
The NGage rear brake pads are designed to provide:
• Progressive braking response without sudden lock-up
• Stable friction coefficient across varied temperatures
• Controlled heat dissipation for consistent braking feel
• Even pad wear for predictable service intervals
• Rotor-friendly surface finish to minimize disc scoring
The friction layer thickness and backing plate stiffness are engineered to resist vibration and maintain stable contact pressure with the disc rotor. This contributes to reduced brake judder and improved pedal consistency during both light braking and heavy deceleration.
Compatibility – Rear Brake Only
These rear brake pads are engineered specifically for the following Yamaha motorcycles:
• Yamaha R15 V3
• Yamaha R15 V4
• Yamaha MT-15
• Yamaha FZ 25
• Yamaha Fazer 250
This listing applies strictly to the rear brake position only. These pads are not interchangeable with front brake pads and must not be installed in the front caliper.
Installation & Service Notes
• Designed for direct replacement of the stock rear brake pads
• No modifications required for installation
• Proper bedding-in procedure recommended after installation
• Brake fluid condition and rotor surface should be inspected before fitting new pads
• Professional installation advised for riders unfamiliar with brake servicing
Correct bedding-in helps establish proper friction layer transfer to the rotor surface and ensures optimal braking performance and pad longevity.
Use Case Guidance
Choose HB 238 (Whisker Ceramic) if you want:
• Smooth braking feel
• Lower brake noise
• Stable performance for daily riding
• Controlled rotor wear
Choose HBS 238 (Sintered) if you want:
• Stronger braking bite
• Higher heat tolerance
• Better performance under aggressive riding
• Longer life in demanding conditions
