Does anybody know where I can find the decceleration rates associated with the B752 autobrake settings.
Yes, I know where you can find that info - in the maintenance manual!
I don't have access to a 757-200 manual but can give you figures from some other Boeing products as a guide only.

1. 4.0ft/sec/sec
2. 5.0ft/sec/sec
3. 6.0ft/sec/sec
4. 7.5ft/sec/sec
MAX. 11.0ft/sec/sec
RTO. Full 3000psi hydraulic pressure to brakes-nil decel rate taken into account, braking limited only by anti-skid system.
767 (steel brakes)
1. 4.0ft/sec/sec
2. 5.0ft/sec/sec
3. 6.0ft/sec/sec

MIN. 4.0ft/sec/sec
MED. 6.0ft/sec/sec
