When you’re installing rear calipers on a Fiat, there are a few things you should be aware of before you start the job. Refer to the illustration at left.
The factory manual suggests that to fully seat the piston (1) in bore, you should push on it with a blunt object, like a hammer handle. Sometimes this works, but sometimes it doesn’t. If it doesn’t, you can screw it in clockwise until the piston is fully seated.
The piston must be in the position shown in the illustration, with the groove (A) at the top towards the bleed screw, and the slot below parallel to the knob (B) on the brake pad (2).
On 124’s, the vehicle’s weight must be on the axles, otherwise the compensator will stay closed and the rear brakes will not bleed properly.
