Often all that makes the calipers left or right is the bleeder valve position. Air rises in the fluid, so to remove trapped air out of a caliper it helps to have the bleeder valve at a high spot. In many brake pairs the same caliper casting is used for both sides, with 2 cast in bosses available for drilling a bleeder hole and only one hole is used, making it a left or right. Sometimes both are drilled and threaded but a proper bleeder valve is only installed in the hole that was intended to be highest. If you put a proper bleeder in both holes you could make the caliper interchangeable, left or right. This assumes symmetry in the rest of the caliper, like the position of the threaded hole for the brake line. Sometimes there are cast in 2 bosses for that as well and only one gets drilled and threaded, again making it a left or right on that basis. Mark

They appear to be identical as to up or down, so either left or right? Are they interchangeable? These also fit the early vanagons, so I thought I'd post it to the vanagon list as well. > Thanks, > Courtney > |
