Aston Martin Brake Upgrade Brackets, it is quite common to upgrade the front brakes on an Aston Martin DB9 or Aston Martin Vantage, the fronts can easily be upgraded using larger 2 part discs and parts from a DBS or similar, see here but to balance the brakes the rears should be upgraded too which is a little more difficult as the handbrake is separate and not radial fitting
Aston Martin Brake Upgrade Brackets
These brackets are designed to allow the fitting of larger rear brakes to an Aston Martin DB9 or an Aston Martin Vantage. the stock rear brakes use 4 piston calipers with a separate handbrake caliper acting on a 330mm one piece disc. The upgraded brakes use a 380mm 2 part disc (2 part discs have a number of advantages, less weight, reduced chance of warping and reduced heat transfer) whilst the large (380mm vs 330mm) allows more leverage from the brake caliper and improved cooling whilst matching the increase in front braking.
