Hi,
I have recently replaced all the brakes disc and pads and front wheel bearings, but after reactivating the SBC (used iCarSoft - confirmed all pressure sensors were reading around 70bar), I found that on driving the car a few meters it became obvious that the front pads were stuck on the discs. I previously checked that the calipers moved Ok when I had deactivated the SBC, and the wheels spun, but did notice there was very little clearance between the discs and the pads. I had also bled the brakes with a pressure bleeder. The back ones bled ok, but the front driver side required more pressure as I had a bit of air in the caliper, but then it was Ok and got a firm brake pedal after removal of the air. The passenger front side did not bleed properly when I released the bleed screw - this was also the side where I had very little clearance between the pad and the disc. I have ordered a new bleed screw in case it was blocked but I am suspicious that the problem might be related to this, but not sure - no air in this side though, as I did not remove the caliper like I did for the drivers side front (hence the air which got in). I checked both wheel sensors as I got C2452 error RHS speed sensor - 'inspect distance from rotor to sensor'. Both gave 9 Mega Ohms when tested on car (wiring clip to sensor).
As I have been at this job for a while and I am not quite sure of my next step (plus it would be great to finish this job!), any comments back would be appreciated!
