Ferrari Mailing List: Re: 308 hand brake problem

[robert_h_bowser [at] juno.com (robert_h_bowser]

If I remember correctly, the lever connects to a shaft that acts mechanically 
to push the inboard piston against the rotor.  There is an external return 
spring.  If the shaft is binding, I think you need to take the caliper off.

Just make sure the binding is not external to the caliper (e.g., spring is 
properly attached, cable is not binding up somewhere).

If you take the caliper apart, remember that you have to get the inboard piston 
out by screwing the little allen screw under the 13mm plug on the inboard side 
of the caliper.  Don't try levering it out (like I did!).

I went to move the 308 today by pushing it and found I could not move the 
swine!
I jacked the back up and found the left rear brake was stuck on.

Upon examination I found the little arm on the caliper that is connected to 
the hand brake had not fully returned when the hand brake was let off....

My question is....
How does the force transfer from that little lever to the pads?
And can I take the lever off starting with the screw on the top to service, 
clean and lub that part without all hell braking lose (no pun intended!) and 
brake fluid going everywhere?

The calipers were "rebuilt" by the main Ferrari agent over a year ago and 
the discs machines at that time all before I bought it.... just looking at 
the dirt around the caliper I am guessing they didn't touch the handbrake 
bit at all...
