Installing a Oversized Disc Brake and Carrier

Let's be brutally honest from the get-go here: new bikes have good brakes on them. Some bikes are better than others in the braking arena, but if we get down to the nitty-gritty of it, they all work okay.

That said, there's no reason why you shouldn't go looking for a way to make to make them better. That's why we thought it'd be a good idea to test the Motomaster Oversized Disc and Carrier.

The whole effort started with the fitting of the disc, which was to be mated with the super-cool Excel Pro-series rims. A dab of Loctite on the threads to stop them coming loose, and away we go. Replacing the standard caliper carrier was also a simple process, with a couple of rubber boots and one bolt needing to be transferred from the standard unit to the new gold-anodized new carrier.

We also applied a bit of grease to the rubber boots to help the caliper self-center. So, that was the fitting, but how have they stood up to the rigors of regular use?The disc itself has an aggressively designed semi-wave look. The small waves on the outer edge of the disc are much sharper than others on the market, and that helps it to clean out the caliper in muddy conditions.

The results from the disc are outstanding. Not only did the disc increase stopping power, but it also gave better feel at the lever, with the rider needing less pressure to get the same results.

But, especially if you have your bike for a long time, it'll take you some time to get used to the extra sharpness over the stock unit.
