[QUOTE="OSFlanker, post: 111473, member: 12"] Upgrading the master cylinder/servo is more than just pedal feel. The actual brake force will have been increased. As mentioned by Jules, this may be dangerous for some as the increased force may cause the brakes to lock easily. Of course Uncle Jules being a master karter can modulate the brakes Michael S. style! Is there any information of the brake force of the E30 brakes? Here are some info on the E34 brake forces which is taken from [url]www.bmwe34.net[/url] : E34 540i brakes develop 686 lb-ft of torque on the fronts at 500 psi line pressure; the rears produce 313 LB-ft, so the f:r bias is 69:31 (as a percentage) E34 M5 US Spec front brakes (rears are the same on US E34 M5's) generates 720 LB-ft, changes the bias to 70:30 E34 M5 Euro spec brakes generate 646 LB-ft front and 336 LB-ft rear, giving a bias of 66:34 As you can see, the brakes are the most powerful instrument on your car (going by the torque figures). As the E34 540i already generate 686 lb-ft of torque, you can imagine the force of an E38 double servo brakes and the potential hazard it will cause for some! [/QUOTE]
