Hudson.I agree.I have experienced brake fade in all the cars I've really put through the paces as well.I agree with the people that say stock 140 brakes are great and ahead of thier time.What some people don't understand (I don't intend arrogance) is that people are asking for brake info because we drive our cars harder and found the need.No offense but most of you havn't pushed your cars to the point of feeling that you NEED better brakes.That doesn't make us better people (maybe more crazy or stupid though).But enough of the mister rogers speach.....
I have updated brakes on 6-7 140's.In all but the last case it was the front brakes only.I installed 164 calipers,rotors and studs (yes,do it right!).There IS a difference.The car stops on a dime.I especially noticed it in my current car with the turbo engine.On that car I also installed 240 rear calipers mainly for ease of parts location in the future (get pads at 7-11 while on the road,get the picture?!) Those needed only to have the mounting bolt holes enlarged and the fittings on the brake lines changed.I also have looked at the 240 front caliper swap.The metal,people have mentioned machining off is on the inside edge of the caliper (the side that contacts the spindle) I havn't measured but hopefully someone will ad the info.I use metal master brake pads (I know brake pads are like Oil,Politics,and Religion).Also interesting to note.The last set I did on my current car I got at the wrecking yard.The pads were thick,I figured what the heck I'm cheap,I'll run them.Having done the swap several times before I knew they wern't "right" when I was done.I surfaced the rotors (still over spec) and changed pads.better,but not where I wanted to be.I installed new Volvo rotors and another set of (metal master) pads and WOW! What a difference.I have experienced the same problem on some 960's and S/V 70's (re the rotors,NOT the pads)in servicing them daily.I'm not saying on all volvos,but on some,VOLVO rotors matter.
