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
- 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
- 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 )
- Refit wheels and enjoy
That wasn't too hard now was it?
