Teams were this week informed of an impending update to rules regarding the six-piston, AP Racing-supplied front calipers.<\/p>\n

Anti-knockback springs are no longer compulsory, while Brad Jones has revealed teams have also been warned against tampering with the piston seals.<\/p>\n

Jones explained the situation in his latest BJR workshop video.<\/p>\n

\u201cThe reason there has been chat about this and clarification is that people are playing around with a couple of things to try and minimise the amount of drag the brakes have,\u201d he said.<\/p>\n

\u201cOne of the things they\u2019ve been doing is freezing [the seals] and machining or linishing (sanding) them to reduce the drag.<\/p>\n

\u201cWhat they try to do is minimise that but not allow it to leak, so it\u2019s quite a tricky operation. They do it in GT cars.<\/p>\n

\u201c[Now] you\u2019re not allowed to touch it at all. You can\u2019t linish it, you can\u2019t freeze it, you can\u2019t play around with it.\u201d<\/p>\n

According to Jones, teams were also manipulating the anti-knockback springs in the name of reducing drag.<\/p>\n

\u201cWhat people are doing is they are putting them in a press, taking all the tension out of them so they don\u2019t push the pad up against the disc so hard,\u201d he said.<\/p>\n

\u201cWhat Supercars have done is make this optional.\u201d<\/p>\n

Jones commended Supercars for stepping in as teams try and eek out every possible performance gain, no matter how miniscule.<\/p>\n

\u201cThis is the sort of stuff that\u2019s going on at the moment to try and find all those little extra bits that add up to something,\u201d said Jones.<\/p>\n

\u201cIt\u2019s pretty clear what you can and can\u2019t do now with the caliper.\u201d<\/p>\n

Supercars undertook brake testing following the last round at Symmons Plains in the name of exploring new pad options for the category.<\/p>\n
