  15. Abs lines

    It does for sure yes, if your not worried about pad wear sensors, a simple bridge wire on this system will knock the light off. I once fitted black diamond pads which didn't have sensors and that's what I did. Worked back then anyhow.

    Most pad wear systems nowadays use the sensor as an earth onto the disc, whereas from memory these are different.

    I've got genuine bosch pads back in mine now with the sensors plugged in.

    I gotta say, it's a mammoth task fitting abs so fair play to you. ECU, looms, excited rings, pipe work, sensors and dash warning system etc.

    Also, number 6 port on pump is the front of master, closest to the engine.

    I should know but I don't for certain, I would think it does matter because it's relevant to the twin line safety system. If you burst a brake hose at the front driver side, you will still have limited braking, on the passenger side front and driver side rear. Opposite corners are normally piped independently. I'll see if I ca trace a bit further later on for you.

    Same goes with the 2 rear lines, they do need to be in the right places for the abs pump to apply and release the correct wheel when a lock up is detected.

    Catch cans are effectively a means of venting to atmosphere, depending how they're piped up. It just means the oil spit that passes through the breathers is collected instead of making a mess anywhere. Just need to empty them out on service.

    Some people run a pipe from the rocker cover to a catch tank, then just stick one of those little mini k&n filters on the outlet, others run the outlet back to the inlet tract. The theory being, that the oil is collected in the tank, and only vapor is passed back to the throttle body.

    Venting to atmosphere does ensure the inlet tract stays dry and oil free.

    This isn't always possible with modern engines nowadays because the pcv valve is somehow vacuum controlled and monitored through the ecu. There is a lad I work with had one fail on a mk5 gti and it gave him an erratic idle.

    Here's how mines routed for the time being, my engine bay is In a state of neglect at the minute so don't judge me lol...

    No problems, it's only there to recirculate crank case pressure or blowby as the yanks call it. It's just what down draft the piston rings cause and any compression passing rings in a poor engine.

    You may find you get oily wishbone because there will always be certain amounts of oil "spit" from the breathers.

    Hence the oil in the ops inlet tract.

    Pcv valve can be removed but it's advised to run your breather pipe to a catch can, or straight out to atmosphere with a piece of long pipe down to the chassis rail.

    That mesh in the pcv valve is intended as a flame trap to stop any unwanted hot oil firing in the inlet tract. Personally I don't really think such a problem is too likely but that's what it's for. It also does a good job of stopping too much oil splatter into the inlet.

    Mines long gone and at present I've got a piece of samco carrying the crankcase fumes down to the road but a catch tank or fresh clean pcv is by far the better idea.
