The NGage HB 150 and HBS 150 rear brake pads are motorcycle disc brake pads developed for Yamaha motorcycles that use the HB 150 rear pad profile. These brake pads are engineered to match the exact mounting shape, backing plate geometry, and friction surface dimensions required by the rear brake caliper used on the compatible Yamaha models. This ensures proper physical fitment, consistent contact with the brake disc, and stable braking performance when installed correctly.

This product listing applies strictly to the rear brake position. Front brake pads for these motorcycles use a different pad code and are sold as a separate product. Rear brake pads play a critical role in overall braking balance, vehicle stability, and low-speed braking control. While the front brake generates most of the stopping force, the rear brake contributes to smooth deceleration, traction control during braking, and rider confidence in slow-speed maneuvers and corner entry.

A properly matched rear brake pad must provide predictable bite, controlled modulation, and stable friction output across a wide temperature range. It must also maintain structural integrity under repeated braking cycles without glazing, excessive fade, or inconsistent friction behavior. The NGage HB 150 rear brake pad shape is designed to meet these requirements while maintaining direct compatibility with the listed Yamaha rear brake caliper system.

NGage offers the HB 150 rear brake pad in two distinct friction material variants: Whisker Ceramic (HB 150) and Sintered (HBS 150). Both variants are manufactured using the same physical pad dimensions and mounting design. The difference lies entirely in the friction compound formulation and how it behaves under heat, braking load, and repeated use.

Whisker Ceramic Variant — HB 150

The HB 150 Whisker Ceramic brake pads use a ceramic-based friction compound reinforced with fiber-like whisker material. This compound is engineered to deliver smooth initial bite, progressive braking force buildup, and stable friction output during everyday riding conditions.

Ceramic friction compounds are known for producing controlled braking response with reduced noise characteristics and consistent lever feel. The whisker reinforcement enhances the internal structure of the friction layer, helping the pad maintain uniform contact with the brake disc surface under varying pressure levels.

This variant is intended for riders who prioritize refined braking feel, predictable rear brake response, and smooth modulation during city riding, highway cruising, and mixed riding environments. The ceramic compound supports consistent friction behavior without aggressive bite characteristics, making it well-suited for riders who prefer a linear and controlled rear brake feel.

Sintered Variant — HBS 150

The HBS 150 Sintered brake pads use a metallic friction compound formed by fusing metal powders under high temperature and pressure. This sintering process produces a dense and wear-resistant friction material with high thermal stability and consistent friction output under elevated braking loads.

Sintered brake pads are engineered to tolerate higher operating temperatures and maintain braking performance during repeated braking cycles, extended downhill descents, and riding conditions where brake heat buildup is significant. The metallic composition offers stronger initial bite compared to ceramic compounds and sustained friction consistency when brake temperatures fluctuate rapidly.

This variant is intended for riders who operate in more demanding riding conditions, carry heavier loads, or frequently ride in environments that generate higher rear brake temperatures. The sintered compound maintains structural integrity and friction performance under conditions where softer compounds may experience fade or inconsistent response.

This product listing covers only the rear brake pad set for the listed motorcycles. Front brake pads for these models use a different NGage pad code and must be purchased separately.

Variant Explanation

HB 150 — Whisker Ceramic Brake Pads
Ceramic-based friction compound
Smooth braking response
Progressive rear brake feel
Stable friction behavior under normal thermal loads

HBS 150 — Sintered Brake Pads
Metallic sintered friction compound
Higher temperature tolerance
Stronger braking bite under load
Consistent friction during repeated braking

Both variants are identical in shape, thickness profile, and mounting design. Only the friction compound differs.

Construction & Design Characteristics

The NGage HB 150 and HBS 150 brake pads are manufactured with a rigid steel backing plate that maintains dimensional stability under braking pressure. The friction layer is bonded to the backing plate using high-temperature bonding methods to prevent separation under thermal stress.

The pad surface geometry is designed to promote even contact with the brake disc, reducing uneven wear and maintaining consistent friction output throughout the service life of the pad. The chamfered edges and surface profile help minimize vibration, reduce brake noise, and support smooth engagement during light braking.

Both variants are engineered to operate across a wide temperature range while maintaining predictable friction behavior. Proper bedding-in after installation is recommended to ensure optimal contact between the pad surface and brake disc.
