Size of nut brake caliper

BillyMG · 2nd June 2018, 12:23

Does anybody know what size the nuts are on the front brake calipers on a cdti? I need to take the hub off - tried a 14mm too small 15mm too big

I've now snapped both a screw and a drill bit in the abs sensor trying to remove it so am back to removing the hub - is it even possible to tap the sensor out with the hub removed before I go to all this trouble? I presume the brake caliper nuts are AF Size??

Also, just a desperate thought, is it possible to tap the abs sensor through the hub from the outside rather than the inside out? If so I could potentially pull the hub off the drive shaft slightly and tap it through...? I'm looking at the new one and see it's thinner at one end tho so presume it has to come out...?

caliper bolts are 15mm definitely and don't take a drill to it until the drive shaft is out , and watch out don't damage the rear of the wheel bearing .

I tried 3 x 15mm sockets and all slipped off so on my 75 definitely not 15mm. Measured the nut with a caliper - 14.34mm

Already screwed a screw in and snapped off with claw hammer. Also snapped drill bit off whilst drilling. Sensor is flush with hub ...

I will take the hub off and see what options are available

Thanks
