Pace RC38 Airforce Forks £85

This is quite common with the Airforce and is caused by the bridge bolts not holding the legs in parallel. This is because when full of air the ends of the push rods are not aligned equally and if the bridge bolts are loose the legs go out of alignment.
To set it right first let all the air out of the fork-bottom two chambers first-then top. The legs should now be free to move without the pressure pushing the rods. Carefully loosen the bridge bolts-the legs can now be moved independently to align the dropouts-use a true wheel with no tyre to check.
The bridge bolts should then be retightened WITH EXTREME CARE as it is very easy to break the magnesium and the bridges[If it is an AF1] are no longer available. 4.5 Nm used to be the torque setting when I was building them, but be careful that the bolt holes are'nt too degraded. It is quite a good idea to remove the bridge, clean the contact points and put a little Loctite or superglue on the mating faces and then bolt it all up.
Then put air back in the fork; top first 60 psi, then bottom 40psi under damper and 80-100psi under top air chamber.
