deja Posted July 14, 2006 Share Posted July 14, 2006 Just how hot does a disc brake caliper get in street use? I want to paint my calipers and have some leftover red Por15 engine enamel which says its good to 450 degrees. Do calipers get hotter than that?

OlderThanMe Posted July 14, 2006 Share Posted July 14, 2006 I would not use it for calipers. I have some caliper paint and I think it it says 1000* safe...I think the calipers get hot enough to where it would affect your paint. Not sure though Quote Link to comment Share on other sites More sharing options...

SHO-Z Posted July 14, 2006 Share Posted July 14, 2006 I got this off of the internet, unless you are into some serious racing in which point you would not paint a caliper anyway, paint is an insulator. The boiling point of the brake fluid a 400° so 450° paint should have no problems. You know that the car companies have a safety factor between the boiling point of the fluid and the temp of the caliper. The properties necessary for quality Brake Fluid are controlled by the major Brake Fluid specifications ie the US Federal Motor Vehicle Safety Standard (FMVSS) DOT 3, DOT 4, DOT 5/5.1, SAE J1703, and ISO 4925. Many OEM’s have their own Brake Fluid specifications while many national standards authorities also have their own, but as a general rule all are based on the FMVSS, SAE or ISO standards. The main differences between them are summarised as follows:- Test Boiling Point Wet Boiling Point* Viscosity cSt ºC, min ºC, min @ -40ºC, max DOT 3 205 140 1,500 DOT5.1 260 180 900 SAE J1703 205 140 1,800 ISO 4925 205 140 1,500 Quote Link to comment Share on other sites More sharing options...
Clifton Posted July 14, 2006 Share Posted July 14, 2006 I used VHT engine paint on some calipers. Never had a problem. I'm sure regular can spray paint would be fine too but VHT is a little better resistant to engine degreasers. Quote Link to comment Share on other sites More sharing options...
2003z Posted July 16, 2006 Share Posted July 16, 2006 You can use the POR15 stuff if its good to 450. I've powdercoated probably over 150 sets of brake calipers, which have all held up fine, and pc is good to 350. Quote Link to comment Share on other sites More sharing options...

Cool, this is from http://www.por15store.com/page/por15/PROD/Topcoats/EE website for their engine enamel "Our Enamels withstand temperatures up to 450 degrees F."

LS1 240Z Posted July 21, 2006 Share Posted July 21, 2006 just use rustolem spraypaint. its what i used on rotors and callipers Quote Link to comment Share on other sites More sharing options...
jgkurz Posted July 21, 2006 Share Posted July 21, 2006 I've used the "VHT Brake Caliper, Drum and Rotor" paint" with great luck. You need to make sure the caliper absolutely grease and rust free. You'll need a couple coasts at a minimum. Quote Link to comment Share on other sites More sharing options...
