Well so I posted a question earlier this evening asking about a bad m/c and brake booster.

Well I took a peek under the hood with a light and it was very obvious that the m/c was leaking. Sadly I didn't catch it in time and it ate away a lot of the paint on my brake booster and even part of my engine bay's paint

To make a long story short I half *** repainted my brake booster with some tremclad rust paint after thoroughly cleaning the brake booster with plenty of brake cleaner and sandpapered the rusted areas and rough paint edges.

In the process of repainting the brake booster I used a heat gun on the highest setting to make the paint dry faster and I was drying the spot with concentrated heat where the m/c would bolt up to. Well I know for a fact that the brake booster had some pretty intense heat on it and after about 3 - 5 minutes of heating it up I noticed that it started smoking!

I quickly stopped and tried blowing cooler air on it but it was obvious that some light smoke was coming out of the brake booster hole. My question is: Are there any "meltable" components behind the front cover of the brake booster or do you guys think it was the grease that was on the brake booster shaft that plugs into the m/c?

After smoking for like 2 minutes I decided to start the car and let the engine pull air through the brake booster hole (where the m/c bolts onto) in hopes that the vacuum draw will cool the internals of the booster off quickly.

There isn't any visible signs of burning of the shaft or the exterior of the booster but now I'm worried that I may have really melted something inside. I re-installed the m/c and bled the brake system and it seems like the brakes are working very well.

Judging by the exploded diagram of the brake booster it doesn't appear that there is really anything on the front end of the booster that could easily melt from a heat gun.

Can anyone shed some light on my little mishap?

Thanks

 

put it all in one thread where it need to be.
