not really, dont you get good discount from ap then???


AP racing were sold off from the AP group some years back, they're now owned by Brembo IIRC. So I don't get discount through work unfortunately, otherwise my car would definately be fitted with their brakes :thumbs:

Some cars (MGB) originally had leading calipers and later models had trailing ones, thus backing up the above theory.

Imagine if the brake caliper was unbolted from the hub. The disc is rotating and the brake is applied. Now if the caliper is rear mounted it will initially go up, front mounted it will go down. So if the caliper is bolted to the hub this force is then transfered through the bearing to the wheel and then to the road surface. So in effect you increase the loading with a front mounted caliper.

lol... why would it???

it doesn't matter where they are mounted... but obviously back mounted ones will make more mess as they throw the brake dust upwards

The positioning is due to packaging restrictions on the vehicle in question, i.e where they have room to mount the caliper due to suspension components etc. In an ideal world all calipers would be mounted at the rear as this would reduce loading on the hub / bearing assembly when braking.

Havent a clue mate... just where they have been designed to go.
