Rear Disc Conversion Option 1


Theres 2 ways to do a conversion, with and without changing the axle. I'll describe how to do it without changing the axle first as it's a step involved in the conversion when changing the axle :)

Cars that interchange using 240mm discs:
Alfa Romeo 145/146 (the donor car I used in this conversion)
Fiat Bravo HGT
Fiat Coupé
Fiat Punto GT (mk1)
Fiat Tempra / Tipo

The front discs from a Cinq/Sei and Punto 8v are the same discs that are used for rear discs.

Now there are others that interchange that I've missed, if you want, leave a comment with the make and model that also fits if you know of another one that fits :)

Youll need:
  • handbrake cables (2 long ones and the short one)
  • calipers+carriers + clips
  • discs+pads
  • hub spacer
  • dust guard
  • appropiate pipes

Budget time for this one (y)

  • First, park up on a level dry surface and chock the front wheels
  • Remove your wheels and drums
  • Remove the exhaust and heat shield right to the front
  • Disconnect all the springs in the drum, remove the shoes and handbrake cables totally
  • Using the 30mm socket take off the hub and spacer
  • Remove the wheel cylinder and plug the pipe up (no fluid leak)
  • Remove the backing plate (allen bolts)
  • Clean everything and prepare to put the discs on

At this stage, I recomend to make your own brake pipes with a flaring tool as the metal pipes are most likely half seized and ready to ring (n)

  • Start with the dust guard, hub and spacer (guard, spacer then hub)
  • Fit the disc then carrier

  • Then the calipers and pads
  • Attach the brake hose and fix it in position
  • Attach the pipe to the hose then remove the old pipe quickly and screw in the new pipe (for minimal loss of fluid)
  • Attach the new handbrake cables, including the one that goes into the handbrake (adjuster) as it is slightly shorter
  • Make sure all is tight and that there are no fluid leaks. Bleed the system thoroughly (the nipple takes a 11mm spanner :confused:)
  • Refit wheels and enjoy

That wasn't too hard now was it? :D
