To add a few comments to Mad (Flt) Scientist's
wise words -
The stresses upon the nosewheel assembly, including the compression forces upon the oleo, are well within the design limits for the assembly. Viewing manufacturer's tests of Vmbe (mbe = Maximum Brake Energy), where brake capability is taken all the way to the limit (very graphic pictures) reveal an 'unconcerned' nosewheel sitting there whilst all hell breaks loose with the main gear and tyres.
The B727 did have nosewheel braking available as an option, my old company did opt for it but progressively removed it in the '80s due to negligible performance gain Vs weight / maintenance cost. I recall that it only added about 500 Lb (227 Kg) to the Accelerate-Stop performance limit.
