I am building up the front uprights on my Sylva J15 (basically Caterham/Triumph origin). I bought the Willwood Midlight and vented disc upgrade and I have a few questions about the hydralic wiring.


Nipples upward

The Midlite has 4 bleed nipples, by their own documentation the lower two do nothing as the air migrates upwards. I assume this design is so the same caliper can be used on both sides.

Questions:

1) The AP Racing caliper on my Westfield has a similar configuration.


AP Racing on Westfield

Is it necessary to add this link pipe to my Willwoods?

2) I note the AP link pipe has a protective sleve, I assume to protect from any stones picked up and redirected at the brake pipe. Is this also a requirement for IVA?

3) Is my sleved pipe as illustrated good choice? ( I can always return the bleed nipples).

Link Pipe at bottom

You knowledgable chaps have a 100% record so far in answering my challenges!

Wilwood's have the lines internal to the calliper, so there's no need for an external pipe. Whilst I can see nothing wrong with having that link pipe at the bottom of the calliper, equally, I can't see any benefit from having it. As you say, the 4 nipples are so they can make a single calliper and use it for both sides.
