Twin-Piston Calipers: Are Two Pistons Better than One?
In 1988, the first dual- or twin-piston floating brake caliper appeared on the Corvette. This was just the beginning for the design that would find its way onto just about every light truck and SUV, including the Chevrolet Suburban and Ford F-series, by the year 2003. Servicing these brake systems is not that much different than servicing the single-piston system. But, there are some things you should be aware of prior to tackling the repair. The floating design may have its problems out in the field when it is neglected, but its does have other strong points. First, a floating caliper is inexpensive to manufacturer when compared to opposing piston designs. Second, it is very compact and easy to package on vehicles. Third, the floating caliper has fewer leak points than an opposed-piston design. Also, it is easily used as a parking brake with either cable or lever mechanisms. |
