How to test brake caliper NOT installed?
I have 4 used brake calipers that were removed from a 300CD but may not have been seized , as the problem turned out to be something else.
Wondering if anyone has an idea how i can test these calipers short of installing them and seeing if they work? Thanks! |

Nothing short of rigging up a test bench which would cost a couple of hundred dollars at a minimum.
Hydraulic pump, suitable hoses, piston retainers (could use a block of wood) and a gauge. This would only test total pressure. Would work only on a single caliper design. Wouldn't tell whether the pressure is applied evenly to multiple calipers. Initial test on a new rebuild uses vacuum but this method can't be trusted on a used caliper due to possible wear on the piston.

If you place a board in the caliper to prevent the pistons from blowing out, you can use compressed air to observe the pistons for proper movement.

Compressed air sounds good to me!
Thanx, Tango Fox, i wil! give that a try.

Define "test". Do you want to test mechanical function and / or leak? How long have these been sitting after removal from the car? Was the fluid drained and ports capped? What was the initial problem that turned out to be something else? |
