Subject: Re: New Member - mr red vette dude - please check in here!!! URGENT! by Churchkey on 2013/1/28 14:36:33 Welcome, very nice ride. It is clamed that C5 brakes work better than C4 brakes because of the C5's increased pad area. IMHO it is because the C5 calipers have a larger piston diameter of 1.62" compared to the C4's 1.5". C5 calipers = a change in the front hydraulic ratio that provides more pad pressure for a given pedal pressure. You can acheive similar results using an eariler year master cylinder with a smaller bore size. Your master cyl = 15/16". 88-91 master cylinder 7/8". While the master cylinder is off the vehicle suggest a DRM brake bias spring be installed it will improve rear brake performance. If you require statistical data on the hydraulic ratio changes I'll pull it off my shop computer. |
