Aero Kool Shimano XTR 2011 Disc Brake Pads

The Kool-Stop KS-D635K is a forged aluminium disc brake pad designed for Shimano-compatible disc brake systems, offering dependable stopping power in varied conditions. With an organic compound formulation and integrated cooling pins, these pads are a practical upgrade for riders across India's demanding terrain — from Pune's Sahyadri switchbacks to the long descents around Ooty and Coorg.

Our Take

India's roads demand brake pads that perform consistently under heat, grit, and sudden rain. The KS-D635K's organic compound bites cleanly without the harsh bite-and-release of metallic pads, making it well-suited to mixed riding in cities like Hyderabad and Chennai where stop-start traffic is constant. The cooling pins on the forged aluminium back help manage heat build-up during long Western Ghats descents — a real advantage when temperatures push past 35°C in summer.

Sizing for Indian Riders

These pads are designed as a direct replacement for Shimano disc brake systems compatible with the D635 series — excluding BR-CX75, BR-R515, and BR-R315. There is no rider sizing consideration here, but verify your calliper model before ordering. The integrated spring ensures correct pad return and alignment, making self-installation straightforward even without a workshop visit.

Compatibility Notes

Compatible with Shimano disc brake callipers in the D635 range, with three explicit exceptions: BR-CX75, BR-R515, and BR-R315. The forged aluminium backing plate with cooling pins is designed for secure seating. Organic compound pads should be kept free of oil and brake fluid contamination — avoid touching the compound surface during installation.

Pairs Well With

Complete your braking system with disc brake rotors, hydraulic brake fluid (mineral oil type for Shimano), brake bleed kits, and disc brake-compatible wheelsets. A torque wrench is also a useful addition for precise calliper bolt tightening.
