they are needed to keep your pads closer to disc/drums
while it may not matter, i have always seen them and installed mine after all other valves
I'm not sure it matters either, but I have never seen them installed other than the following order - mc, residual pressure valves, other valves (such as a proportioning valve), then caliper / wheel cylinder. This is how I have them on my T. Just the opposite of how Ogre has seen them if I read his post correctly. Just goes to show ya' I guess when you're asking for advice on a public forum LOL!!
