  1. I realise that this is probably a newbie please go gentle.. When operating the twin piston Tokico calipers are both pistons supposed to move together in a linear fashion.. Or is the caliper designed to allow one to operate until it meets resistance at which point the hydraulic pressure acts upon the second piston. I'm asking due the way my OSF caliper is currently operating. With the caliper removed from the hub and hung up - pressing the brake pedal causes the upper most piston to operate (move out) but the lower one remains static. If I then chock the top piston with a piece of wood and operate the break pedal again - the the lower piston does start to move. My thought are that they should both move in sync. The OSF front wheel/caliper/disc are getting pretty hot after a short journey so checked the caliper for movement and found that the top 'slider' was really stiff so replaced it and drove the car again, but same thing happened. It now looks like the disc(s) and pads need to be replaced as the OSF disc has a blue tinge to it from the excessive heat. It appears as though the lower piston is partially seized and a caliper rebuild is required. Could one of you help explain the caliper operation and whether my diagnosis is correct please. Cheers
