firemansim Posted July 30, 2013 Share Posted July 30, 2013 Are grooved discs "handed". Some say they should be fitted so they throw out the brake dust and others say the complete opposite that they should be fitted to "collect" air. Quote Link to comment Share on other sites More sharing options...
Tinyflier Posted July 30, 2013 Share Posted July 30, 2013 I thought it was decided on by the manufacturer ie legitimately varies? David Quote Link to comment Share on other sites More sharing options...
AliveBoy Posted July 30, 2013 Share Posted July 30, 2013 depends on the spec etc of the disks. I'd recommend reading the gumpf which came with them or looking at the manufacturers website Quote Link to comment Share on other sites More sharing options...
Ekona Posted July 30, 2013 Share Posted July 30, 2013 Don't go on which way the grooves go, you go by which way the vanes inside go. That's what cools the disc, and fitting them the wrong way round will kill them quicker than Greekman can. As above though, check with the manufacturer.

ZMANALEX Posted July 30, 2013 Share Posted July 30, 2013 Vanes should point backwards if the design allows. Alex. Quote Link to comment Share on other sites More sharing options...
Ekona Posted July 30, 2013 Share Posted July 30, 2013 I spent 10 mins trying to figure out how to say that without making it complicated, and gave up. Then along comes Alex and does it first time 1 Quote Link to comment Share on other sites More sharing options...
