clear coating brembo caliper

**Gotti** · 01-30-2012, 07:46 PM

So im in the process of repainting my brembo. My question is will brake fluid or brake cleaner eat or discolor the clear coat when I install and bleed the calipers?. I will be using clear engine enamel.

Brake fluid will eat away paint. When you bleed them, just hook up some extra vac or boost line to the bleeder valves, so you don't get fluid everywhere.
Here is some info
"Brake fluid, particularly DOT3 and DOT4, can eat away at your car's paint. Eventually, the paint tainted by the brake fluid will flake off from the vehicle and then give rust a chance to attack the body of your car!
However, DOT5 will not eat paint ( DOT5.1 will).

One particular ingridient of brake fluid is the Polyethylene glycol, which is also found in some solvents, is very corrosive to paint."

I was gonna say, the DOT5 we use at work on the air-over-hydraulic friction brake system on the older trains eats the hell outta that paint, when they tear down the actuators that engage the brake calipers they let 'em soak in their own DOT5 so the paint comes off easier in the hot tanks.

Dang lol. From personal experience and just common sense, I would not let anything that is solvent based or has a solvent in it touch the paint on the car(unless it is for paint care) I had some DOT 3 fluid I use in my $3k mountain bike get all over the rear end links of my bike, and it made the anodized paint dissolve off. I was beyind pissed.
