[xj40] Rotor bolt

Hello All,
Happy 4Th of July, and may all in or out of the USA enjoy.
I did front brakes on the 94XJ40 this morning. I’ve never done them on this
car. When I took the front wheels and calipers off, there was not a keeper
bolt for the rotors. What’s up with that.
Did the 94’s not require its installation? Everything was reinstalled, wheel
lugs at 75 ft. pounds and the car drove great, but just a little concerned
about the bolt. Your thoughts please.
Best,
Reggie
94XJ40

Reggie,

By ‘keeper bolt’, do you mean the countersunk-headed screw that
holds the rotor (disc) on to the hub?

That is only a new build production fit item to hold the rotor on
to the hub as the car progresses down the track before they fit the
wheels. The rotors are properly held on to the hub by the wheel
(lug) nuts when the wheel is finally fitted and torqued up. That’s
another reason why it is important to correctly torque the wheel
nuts as you did.

In fact, if you buy new aftermarket rotors, Brembos for instance,
chances are that they don’t even have a hole for that screw.–
