I did the fluid change this morning, using the method suggested by Larry Perkins: it worked like a charm on all wheels, so it means no problems with the brake lines. I first emptied both sections of the master cyl reservoir and filled it with new fluid, then did the wheel sequence as he suggested. At first the dripping was slow (gunky stuff came out) on each wheel, then faster as the liquid cleared. It took about 1 hour to do the complete process.

I took out the old pads and was about to move the cyls in the calipers around, as suggested by Larry... but noticed that the rubber rings from the calipers (the ones that push on the pads) were worn out unevenly on both rear calipers... this causes the pads to push against the rotors at an angle, therefore wearing the pads at an angle... So these calipers either need to be rebuilt or I need to get a different pair...

What's your take guys, does it make sense to get my calipers rebuilt locally (by some local professionals) OR should I just dispose of them and go ahead and get a different rebuilt pair? Throwing away the ones I have to get a rebuilt pair seems a big waste to me: why not having mine rebuilt? And it should save me some money too... What do you think of it?

Thanks,
Rino
