The aluminium Mazda FC3S RX7 Turbo II 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.
Parts additionally needed to make the conversion:
- Mazda RX7 FC3S (Turbo II/Series IV 5 stud models) calipers with short hard lines.
- 4x M12 x 1.75 40mm regular cap screw (included in RD5002029DVS)
- 4x M12 x 1.25 40mm regular hex bolt (included in RD5002029DVS)
- M12 spring washer (included in RD5002029DVS)
- Brake distribution block plug
- Volvo 740 Turbo brake rotors. 22mm thick, 287mm (11.25") dia.
