How do you guys do it in 40 mins...
See jacking up and preparing tools takes 1 hour. Then each side takes 40 mins. You remove, tyre , caliper, clips, pins, pads then clean and grease. Then everything back in. 40 mins to 1 hour each side. And putting back the clips is a pain. Also, you need to rewind the piston. And if you over fill the grease, then remove it again as pads won't go in... 40 mins... no way.
