The Aging rubber break lines to each of the calipers decrease performance and should be replaced along with the rubber line that connects from above the rear diff to the hard line at the back of the VX. INDY 4X4 HAS a full set of sletainless braided lines that will improve breaking. Brake fluid should also be bled every couple of years to maintain braking performance. The breaks and rotors are only parts of the whole breaking system. The OEM break pads are worth the extra $ because they last much longer, they also stop better than other pads I have used in the VX's I have. Dollars are better spent on high quality break lines, vs. slotted or drilled rotors, as well as high quality calipers as needed. Nothing looks better than stopping short of a an accident or close call that could turn our beloved VX's into scrap.
