9000 brakes on a C900 - how I did the plumbing
Posted: Sun Mar 25, 2007 10:17 pm
I fitted one of the 9000 calipers to my T16S today and since there has been discussion here bfore about how to connect the hoses, I thought I'd show how I did it. I'm sure I'm not the first to do it this way but I haven't seen a photo of this method before.
The 900 caliper (on rear-handbrake cars) has a rigid pipe from the caliper to a bracket mounted on the caliper, which is connected to the flexible hose. The 9000 caliper does not have this bracket, nor anywhere to mount one, and the hose will not reach. You can't mount a bracket on the caliper carrier as the caliper moves relative to this as it slides to take up pad wear and a rigid pipe would eventually fracture.
I looked at making a longer hose out of two shorter ones (I have some spare hoses for a Golf, of all things) but it would have come out too long. So instead, I decided to reverse the hose and the rigid pipework to come up with arrangement in the photo. The brackets could probably be a bit shorter but nothing touches throughout the range of steering and I don't think there are any clearance problems through the vertical range of movement either. The bracket itself is held by one of the M8 nuts that holds the ABS sensor cable bracket onto the inner wing. The hole at the other end for the hose fitting is 10mm. The fluid visible on the right leaked out in the short gap between removing the old hose and fitting the rigid pipe. It doesn't leak now it's all tightened up. Honest
An advantage of doing this instead of a longer flexible hose is that standard hoses will still fit (albeit they are fitted "backwards")so there are no complications when they need renewing.
Anyway, the other one should be a lot easier now I've done the working out and made the brackets.
Trollbooster, have you done yours yet?
