Si_s Supe Posted March 19, 2014 Share Posted March 19, 2014 I'm currently overhauling my brakes. Got some Toyota discs and pads en route at the moment. If I etch prime and hi temp black the entire discs and then fit them, would the paint contaminate the new pads as it's removed from the braking surfaces or would it just burn off?? Going to be impossible to judge where the pads would contact the disc and then mask that exact area. Quote Link to comment Share on other sites More sharing options...

scott87 Posted March 19, 2014 Share Posted March 19, 2014 Um yer. Dont do this........ Fit them. Let the air/water show you the areas that will corrode, then paint these bits! Quote Link to comment Share on other sites More sharing options...
Digsy Posted March 19, 2014 Share Posted March 19, 2014 If you MUST paint them, then run them for a while and then paint ONLY the bit where the pad doesn't go and the bit that the wheel doesn't clamp on. Quote Link to comment Share on other sites More sharing options...

In other words it's pointless then. Quote Link to comment Share on other sites More sharing options...
David P Posted March 19, 2014 Share Posted March 19, 2014 (edited) No paint would survive on the rim. Edited March 19, 2014 by David P (see edit history) Quote Link to comment Share on other sites More sharing options...
scott87 Posted March 19, 2014 Share Posted March 19, 2014 In other words it's pointless then. The center bits that rust look poo. So that is worthy of doing. the disk lip itself etc not sure that this would be worth it. Also adding any substance near the brake system isn't really great imo. I would paint the middles and leave the disk face alone. Quote Link to comment Share on other sites More sharing options...
supra joe Posted March 19, 2014 Share Posted March 19, 2014 Why would you want to paint a part that is there to save your life ? I can understand calipers but I'm pretty sure that painting the discs will not help your braking abilities. Quote Link to comment Share on other sites More sharing options...
charlton Posted March 19, 2014 Share Posted March 19, 2014 The paint on the disc would score off as the disc wears away Quote Link to comment Share on other sites More sharing options...
scott87 Posted March 19, 2014 Share Posted March 19, 2014 The paint on the disc would score off as the disc wears away It would. But i doubt very much the pad manufacturer accounted for the chemicals in the paint to come into contact with them...... Wouldnt be worth the risk imo!

ripped_fear Posted March 19, 2014 Share Posted March 19, 2014 Just fit them and use the car for a few days, it will soon be clear where you can paint and where you shouldn't. Quote Link to comment Share on other sites More sharing options...

P_Bazz Posted March 19, 2014 Share Posted March 19, 2014 (edited) I think he means the parts around the hub as those often rust due to the heating and cooling down again. As said before, can't be done with brand new disks as you would never know the area where the pads make contact with the disks. Other than those parts they can easily be painted with some heat resistant paint. Done this myself, no change in braking power whatsoever.

Digsy Posted March 19, 2014 Share Posted March 19, 2014 In other words it's pointless then. On the fronts yes. On the rears you could paint the outside surface of the handbrake housing. Quote Link to comment Share on other sites More sharing options...
Stonkin Posted March 20, 2014 Share Posted March 20, 2014 Just paint the hub of the disc before you fit if you want to. Its fairly obvious where you can paint up to, without applying any paint to the area where pads will go. Quote Link to comment Share on other sites More sharing options...
Si_s Supe Posted March 20, 2014 Author Share Posted March 20, 2014 Thanks guys. Yes, obviously, the idea behind paint is to stop the hubs looking rusty and crap! Not to have the whole disc black!! Lol. Quote Link to comment Share on other sites More sharing options...
Si_s Supe Posted March 20, 2014 Author Share Posted March 20, 2014 Actually, thinking back to when I rebuilt and painted the UK calipers on my old TT6, the new Toyota discs I fitted came with the hubs painted as standard! So, hopefully these ones will too. Not arrived yet though. Quote Link to comment Share on other sites More sharing options...
james_cbr Posted March 20, 2014 Share Posted March 20, 2014 some new discs come fully painted for some cars we have in at work soon as its been up the road to bed the brakes in the paint on the face it gone but the hub and edge stay painted for a long time Quote Link to comment Share on other sites More sharing options...
