NOW FOR the front! We need some extra help here to lift the front wheel off the ground, so my trusty Halfords trolley jack comes into play. I’ve had it for about 15 years and it’s done great service – recommended.

Before we lift the front wheel though, crack off the front axle pinch bolt, main axle, and caliper bolts, so you’re not heaving against tight bolts with the bike in the air – you can risk toppling the bike over. The front axle pinch bolt is a 6mm Allen bolt, calipers are 12mm hex-heads and the axle itself needs a 14mm Allen bit, or suitable front wheel tool. We removed the front wheel speed sensor here too – it’s just one small Allen bolt and it gives more clearance for the wheel to come out while removing the chance of any damage to the little sensor body.

Once the axle and calipers are loosened, carefully lift the front with the jack, just enough to get the wheel up. Remove the calipers, hanging them carefully to one side (ideally with a bungee or similar) so you don’t stress the hoses, and unscrew the axle. This was a bit tight, and I had to tap it through with a mallet and drift to get it moving. Lift the wheel down and out – you might need to loosen the front mudguard depending on how much clearance you have.

Again, loosen the disc bolts carefully and evenly, using a good Allen bit. When the discs came off, we again weighed them, and the stock discs weighed 1,350 grammes each, with the Galfers weighing 1,218 grammes. That’s less of a difference than the rear – just about ten per cent. But there are two of them of course, so we’re saving a total of 264 grammes on the front end, around half a pound of spinning bouncing mass. Good work.

Remember the Loctite on the bolts, and check for any damage, replacing where necessary. Torque the bolts up to 18Nm (13ft lb), repeat on the other side, and you’re done. Refit the wheel, calipers (after changing pads to match the new discs), and torque everything up (all the settings are on the first page). Not with a hammer.

We’ll report back on how the new brakes feel once we’ve done a few miles…
