Hey Guys,

I am about to change my brakes and I painted last year my calipers but the paint faded and I want to repaint them. This time I want make it a bit better so I don't have to redo it again next year.

Looking at the caliper I want to take out the entire thing - clean it and paint it. For that I need to remove the brake line.

Studying the brake hose removal sheet it seems I have two attack points - either on the brake pipe or the bleeding valve but whats the preferred / easier way?

BRAKE HOSE (FRONT) REMOVAL/INSTALLATION
Be aware that most caliper to brake-hose connections have a one-time-use copper crush washer for a seal; I've not checked my "6" in this regard but I bet it has them. Do not attempt to re-use these washers; it will leak! The good news is that they're cheap, the bad news is that finding out that you don't have them and need them when you have the car in the air and the wheels off is not exactly a good thing.... in an emergency you *might* be able to clean and anneal the old washer with a torch, but that's a last-ditch field-repair thing that I strongly recommend against since buying replacements costs only a few bucks.

You need to be extremely careful when pulling calipers and similar on newer vehicles with ABS; if you get air into the ABS pump it's hell to get it out without a dealer-specific scan tool that can cycle it. I have the ability to do that with VW vehicles as I have a HEX-CAN interface but with my "6" I do not, so take care not to allow the reservoir to drain all the way or air to get back up the line toward the ABS pump.

You can try painting it on the car again? Remove caliper and bracket (you can spray bracket off the car), then take a wire brush and scuff up the old paint (don't scuff the rubber seals), then blast it with some brake cleaner, wipe it down, use some self-etching primer, then paint, then clear coat... Don't forget to cover and mask for overspray.

Or if you go the route of removing everything, remove the hose from the caliper side (bolt 4 in the pop-out diagram)... the hard line side requires a special line wrench (do NOT use a regular wrench cause you may strip the bolt). Make sure to leave the brake reservoir cap ON/CLOSED and hang the lines as high as possible to minimize gravitational leakage.

I've reused copper washers on the cars I've painted, but of course you do everything at your own risk and I take no liability for any injuries or damages.

Here's how mine turned out...

Nothing wrong with self-etching primer, home depot spray paint, and clear coat. These lasted a couple track days and a year or two.

Rule of thumb is your paint's longevity depends on quality prep work
