|
The aluminium Mazda caliper has a significant weight advantage over the cast iron Volvo 240 caliper, features a larger pad area, and the advantage of a larger front brake rotor makes for an ideal conversion on 240 series Volvos.
Improved stopping distances and the ability to repeatedly brake from high speed, lap after lap as well as easily available peformance brake pads and the use of an off-the-shelf Volvo 740 Turbo front rotor are some of the advantages.
The Mazda caliper only has one brake line feeding it making bleeding an easier process. Two of the front brake ports in the brake distribution block need to be blocked with plugs.
Standard Volvo 240 flexible brake lines can be used and short hard lines from the caliper to the strut tube can be used with minor modification/reforming.
The 740 Turbo rotor requires minor modification for use with this conversion, the stud holes in the rotor need to be enlarged to clear the larger diameter wheel studs of the 240 hub.
We suggest that customers can source their own calipers from Mazda wreckers in Australia or overseas, however we may be able to offer suggestions on where to source calipers from depending on your location.

Mazda RX7 Turbo II turbo (5 stud models) calipers and short hard lines.
