OK so got a rear brake conversion kit from hi spec cost £2000 to build the front and rear. Excluding machanic costs. The front went on perfectly. Abs rings fit lovely. Now the rear was done today. I've had to leave the handbrake of because the cables they sent don't reach even tho it's designed specifically for the puma. Fuming... Anyway also the original abs rings that fit in the existing drum are to big for the new hub that converts it to calipers. That's not the only thing now when I pull away it kinda does a grinding noise once and pulls back a bit. I've spent so much on this car it's unreal. But it's got no rust, I've had it since 2016. Is this something to worry about. If I live it in gear when parked because no handbrake it seems to be worse. Grinding noise and pulling back. I've had the bearings changed but the abs rings are not in there
