brake lines leaking

Hi there,

You will have to ensure that the pipe connection is very clean and tight, look at both old and new to ensure that they are the same type of union, this will not allow you to bleed the brakes and it can't be driven until it is repaired, normal machining won't work on these rotors they must be surfaced ground, and there is no advantage what so ever in standard road use, in road use they are purely for looks only. Here are videos to help you make your own line or replace the brake flex hose.

The process is the same in most cases.

I went to change my rear brakes on my car this evening and everything went smoothly except when everything was replaced and reassembled and tried out the brake pedal, thinking I might have forgotten to tighten the bleeder bolt, I got under and checked. There was a new, substantial puddle of fluid but the bleeder bolt was fastened tightly. I wiped it down and repeated the brakes and it almost looks like the fluid is coming from the cable under the caliper assembly, the ebrake cable I think. I'm pretty sure there is no fluid in a cable but I'm otherwise stumped.

The only place it can be coming from is the caliper it self, sometimes when pushing back the piston you can damage the seal, to make sure drop off caliper but leave pipe connected, place a piece of wood between the pads and have someone apply the brakes, was down and watch for any leaks, you should see it if it is leaking.
