Front brakes - options
Worzey - 28/12/07 at 01:18 PM

I've got sierra/granada 260mm vented front discs on my Velocity.

I want to lose some weight and thought I could replace these with the Wilwood Sierra replacement kit (here) but with drilled and grooved discs.

But, what is the impact of going from a vented to a single disc. Will it have a significant effect on the braking effect or was it over braked to begin with?

I'm assuming this would save a huge amount of weight.

Braking wise, I doubt you'd notice any difference. You will however notice the much reduced weight and associated gyroscopic forces and the steering will feel much lighter and sharper.

See the Rally Design catalogue it has a section on brakes by their senior designer and he states drilling and grooving is a "fashion accessory"

I've got solid discs on the back and they get seriously hot.

Racers on here before now in these types of discussions have always said that solid fronts are quite enough braking for something the weight of a seven, if you go vented you just add unsprung weight and make your handling worse.

You might find that braking feel improves due to the fact that the discs will warm up quicker. The Powerlites are a good caliper and the Smart pads are good all-rounders.

Sounds like your rear brakes are binding

I personally wouldn't drill or groove a disc but it has some value in the wet particularly for long distance motorway trips where you get slime build up on the disc. If the pedal hasn't been pressed for 20 odd miles you get a heart stopping delay before the brake pads bight.
