Set consists of 2x Tech4 levers, 1x V4 brake caliper (front), 1x E4 brake caliper (rear).
(Pistons in the E4 are minimally smaller)

Hoses can be used, only new pins/olives are needed, as I had to cut them for disassembly. The brake was on an XL bike, so it should be sufficiently long.

Brake was barely used and is in very good condition.
