    Brake System Questions - Replacing Front Calipers/Lines

    Guest-only advertisement. Register or Log In now!
    Im putting Macan 345's on the front. I have all the parts ready to go including new jounce lines. I've read several things about bleeding for this car. I have plenty of experience with brakes, bleeding and replacing things, not the issue.

    Info I have so far:

    There is a VCDS process for bleeding the ABS module. (?) Do I need to do this? (thinking not...)

    I read that if you depress the brake pedal prior to opening the lines, there will be very little gravity drainage. Seems strange but... read here

    If I minimize the drainage, I can just do a standard pedal style bleed and be fine.

    Also, DOT 4 is the correct fluid? I bought Pentosin.

    Thanks. Just looking to do this right the first time.
    There are many like it but this one is mine... (Coming Soon) ;)

    As long as you dont make my previous mistake of pumping the brakes while the line is open ( a natural habit when I get in the driver seat), you wont really need to bleed the ABS module. Once you disconnect the brake line, put a plastic cap to stop the dripping, and make sure the reservoir is always to the full mark. In my case, I had to do tons of bleeding and ABS bleeding because there was basically air pockets all over the font lines. Took for EVER to take most out, and I still see some bubbles a year later....

    Once you put in the new calipers, just bleed as usual, it would take a while so I would buy a power bleeder to do it.

    I always buy brake fluid from the dealer, dont take chances with that.

    After the first bleed, or when brake fluid comes out 100% clear, you can recycle the brake fluid for the next bleeds. Get like 3 bottles and go from there. Just avoid air exposure, leave all bottles closed, etc

    If you empty the old fluid from the reservoir, you need to bleed the ABS module. If you have OBD11 or VCDS its easy to do.
