New front discs and pads

Pagid RS14
Apparently I didn't change the front pads in time, so one of the discs had some ugly grooves a bit too deep for my liking. They're probably fine but I changed them anyway together with the pads. I also had a brake judder I was hoping to finally get rid of.

I found my left brake caliper had scars from a wheel bearing miss-hap a couple of years ago. I suspect that could have caused the pads to jam and that the brakes did not take evenly on the fronts. The pads on the left wheel was only half as much worn as on the right! Glad I found it and was easy to fix with a rasp.

After a test ride on a dark highway I found all brake judder was gone! It seems the new brakes has a more distinct "bite-point" than before. I don't know why because I had exactly the same model of pads and disc before. Maybe that's just while they're new.

Brake disc to hub torque: 35Nm + loctite

Brake caliper torque: 47Nm

Castellated nut torque: hand tight

Clean the new discs with brake cleaner

Grease bearings with high temperature grease while you have the hubs removed.

It is also a good idea to air the brakes while you have the wheels off.

Both the discs and the pads need to be bedded in.

  1. Hi Niclas, hope u are well. Has your csr got a washer in between the front brake calipers and the upright were the caliper bolts on?
    How did the DS3000 pads feel all round ? Last time we spoke on email you had just fitted them. Are u still in the standard brake master cylinder?
    Thanks Andrew (eck5980)
