Rear Wilwoods
AdamR - 8/1/09 at 02:20 PM

Anyone fitted the Powerlite handbrake calipers to a Sierra disc-braked rear end? Rally Design only advertise a kit for drum-braked Sierra hubs. I'm trying to work out which extra bits I'd need over the basic calipers.

Any pics would be appreciated.

Cheers

They do one, it's not advertised online though - watch out though, it doesn't fit the cosworth rear end without mods...

Thanks Cloudy. Have you worked out the necessary mods? Don't want to go on a wild goose chase for the non-Cosworth hubs unless I have to...

MNR supplied me with Wilwood handbrake calipers, ally caliper mounting plate and sierra disk brake type hub carriers. The ally caliper mounting plates bolt over the hub carriers mounting holes. The caliper then bolts radially to the mounting plate. Watch it though as the plates will not pass over the hub so must be put in place on the carrier before the hub is mounted into the carrier (bearings) and the stub axle inserted. I made this mistake the first time and had to disassemble the hubs. I'm ready to reassemble them but must wait for a couple of replacement bearing seals as I damaged two when disassembling. I also took the opportunity to cut off the original Sierra caliper mounts from the hubs to reduce unsprung weight.

I fitted some to a cossie rear end using the cossie hubs but had to modify the mounting bracket,I'll dig some pics out of how I modded the bracket for you,it wasn't too bad a job to do.

I used the kit from rally d , everything bolted on fine to the sierra 1.6 drum braked rears.Only mod i had to do was machine the hub down acouple of mm in the lathe cos the bell part of the disk in the kit is slightly smaller.

Cool. This sounds like the drum based kit from Rally Design. I'm guessing a Sierra drum hub carrier is pretty much just like the disc one, but without the caliper mounting holes. Anyone? Hence you just use as if on drum hubs and lop off the old mounts.

Perfect, thanks. Looking forward to seeing some pics...
