Painting brake booster

[JoshT]

I painted my reman booster with VHT brake caliper paint thinking it would hold up better to potential leaks and spills of brake fluid. The paint recommends baking at 200 degrees for 1 hour to cure to increase durability and chemical resistance. What do you think, will it be safe to bake a brake booster? How about a lower temp for a longer time? No biggie if it ain't it can't hold up any worse than the factory booster paint.

Given that the primary mechanism of the booster is a rubber diaphragm I would be hesitant to bake it at 200* for 1 hour.

100* for 2 hours wouldn't be much different than a 100 mile trip on a hot summer day though. Or sitting in the parking lot on a hot summer day. That I think it would survive.

Yeah, I'd refrain from baking the booster at any temperature...I painted mine with just ordinary rust paint about six years ago and it is still as blue as the day I painted it...the calipers I painted with high heat paint and they are still holding up pretty good...same as the rear drum backing plate...it hasn't rusted over at all and the paint stuck really good to it...I will take pics of it when I get around to replacing the wheel cylinder...and give it another shot of paint if it's gotten any worse than the last time I looked at it...
