The HOPE HBSP204 brake pad retention pin is an original replacement part designed to guarantee the safety and reliability of your Hope hydraulic disc brakes. Manufactured from high-quality steel, this threaded pin ensures a firm locking of the pads in the caliper, preventing any unwanted slippage during intensive braking. Compatible with a wide range of Hope calipers (V4, E4, RX4, X2, M4, Moto, Trail Zone…), it can also be used on Formula Mega and Echo TR calipers.

Technical specifications

• Robust steel construction: material resistant to wear and corrosion for optimal longevity, even in the most demanding conditions (mud, rain, prolonged descents).
• Fine M5 x 0.8 mm thread: ensures precise and secure screwing into the caliper body. The hexagonal head allows controlled tightening using a standard Allen key.
• Length of 26.6 mm (excluding head): exact original dimensions to fit perfectly on the relevant Hope calipers.
• Integrated safety hole: located at the end of the pin, it allows insertion of a retaining clip (HBSP171 clip, sold separately) which provides a second level of locking against accidental loosening.
• Featherweight of 2.5 g: negligible contribution to the total weight of the braking system, in line with Hope's philosophy of optimizing the weight/performance ratio.

Extended compatibility

This HBSP204 pin is compatible with the following Hope brake calipers:

• Hope V4 (all versions)
• Hope E4 (2013 versions and later)
• Hope RX4 and RX4+
• Hope V2 and Moto
• Hope X2 (threaded models, 2009 and later): Race Evo X2, Tech Evo X2, Race X2, Tech X2, Tech 3 X2, Tech 3 X2 Uno
• Hope Mono M4 (2009 versions and later)
• Hope Trial Zone and Race
• Extended compatibility: Formula Mega, Echo TR

Warning: this pin is not compatible with other Hope brake models (notably older Mono Mini or V2 models without threading) nor with brands other than those mentioned above.

Installation and maintenance

• Simple assembly: the pin is screwed into the caliper using an Allen key. It passes through the brake pads and ensures their lateral retention.
• Recommended securing: for maximum safety, install the Hope HBSP171 retaining clip (sold separately) in the hole provided at the end of the pin. This clip prevents loosening in case of vibrations or impacts.
• Regular inspection: periodically check the tightening of the pin and the condition of the clip, especially after demanding rides (DH, Enduro, trials).
• Preventive replacement: if the thread shows signs of wear, deformation or corrosion, replace the pin immediately to guarantee the safety of the braking system.
