I recently changed the front brake pads on my 954rr. Firstly I noticed the lever became a little 'squishy' after the pistons were pushed back to fit the new pads. I don't know how air would have entered the system given I didn't see any leaks. Anyway I understand I'll have to bleed the brakes? My procedure will start with cracking the banjo bolt to bleed the master cylinder and then onto bleeding at the calipers. Please let me know if that's right. Anyway on a test ride I noticed that the brake lever pulsates. This never happened before the pad change so I highly doubt the rotors are warped. Could this pulsing or 'grabbing and slipping' be associated with air in the lines, as above, or another issue? Thanks.
