Designed as a high-performance upgrade over the standard D630, these pads are built for riders who push hard on descents and need reliable, consistent stopping power.\u003c\/p\u003e\u003ch3\u003eOur Take\u003c\/h3\u003e\u003cp\u003eIndia's mountain roads — whether you're dropping into Lonavala from the expressway, threading switchbacks above Ooty, or grinding down the Coorg ghats — demand a brake pad that holds its composure under sustained heat. The KS-D630S's sintered compound bites hard and resists fade even when repeated braking builds temperature, making it a strong choice for loaded touring riders and aggressive descenders alike. The copper-plated backing plate adds durability that cheaper pads simply can't match over a full monsoon season.\u003c\/p\u003e\u003ch3\u003eSizing for Indian Riders\u003c\/h3\u003e\u003cp\u003eThese pads are designed specifically for Shimano BR-M965 and BR-M966 disc brake calipers.

The spring is included, so installation is complete straight out of the packaging.\u003c\/p\u003e\u003ch3\u003eCompatibility Notes\u003c\/h3\u003e\u003cp\u003eCompatible with Shimano BR-M965 and BR-M966 disc brake calipers. The sintered compound is suitable for both wet and dry conditions, including monsoon riding on Indian roads. Includes retention spring.
