Thread size question

Recommended Posts

Do you know what the thread sizes of the different bolts used to hold, principally 90 rear and 110 front calipers on to the axle are?

I'm making fiddle brakes at the moment and I need to tap the bracket which bolts on to the axle with an appropriate thread. The brackets will take RR Rear or 110 front calipers and although I have both calipers,I dont have any of the bolts to guess the thread from.

Any ideas would be appreciated.

From EPC

Defender front & rear from VIN LA930456 M12 X 35mm

RR Classic Front & rear UNF 7/16" or M12 x 35mm

doesn't tell me thread pitch, I assume standard 1.5mm pitch on the M12 bolts

hope that helps :D

7/16" UNF is 20TPI if that helps
