Brake Upgrade

[Hacksawcats]

Hi Anyone got any recommendations for brake disc upgrade for 2005 1.6 VVT. Discs are knackered with only 30K !

You could really only change to quality items like Brembo, with matching fast road pads. Obviously drilled discs look good, but the only real upgrade is gained by changing the callipers.

Hi Rob, again thankks for the reply, could you please explain why uprgrading the calipers would help? and any recomendations?

As you might imagine with items that are "out of sight and often out of mind" these parts are built to a price. Upgraded items are better quality and to better tolerances. Giving more power and a better feel at the pedal. A popular trick is to use something from a bigger model as the discs are often bigger and give a bigger swept area, also the calipers will flow more fluid allowing for more pressure for a given pedal movement.

Bigger pistons -- The larger the pistons are, and the greater the area over which they come in contact with the brake pads, the more clamping force they have on the rotor.

More pistons -- Low-end floating brake calipers have a single piston, on the inboard side. Low-end fixed calipers have a single pair of pistons, flanking the rotor disc. High-performance calipers can have multiple pins or pairs of pins, mounted on opposing sides of the rotor. Six-piston models are increasingly common and even 12-piston models are not unheard of. Increasing the number of pistons also serves to increase the clamping force of the caliper.

Hope this helps
