Hey Guys,

I am dealing with a Jaguar Kougar that sourced parts from an MK2 so I figured I would give it a shot and post here. Please let me know if the components look different than an MK2 (E type, something else).

I am doing a brake job on it and noticed that when the wheels are fully turned, the rotor appears to rub on the very top of the control arm (note: it is shown slightly away from disc in the picture. I have circled the area in red. I am assuming the bushings are probably out but I figured I would seek the great minds of the Jag Forum. Let me know what you guys think the problem could be / have any experience.

Thanks for your help,
Ben

 

The Mark I & II have a recirculating ball steering box and has adjustments on the steering links to increase or decrease the stops of the total steering movement to prevent rub. By your picture, it looks as you have rack and pinion. Can't see by pictures if you are actually rubbing the rotor, but if you are full lock in first picture you are close but not rubbing. You might check alignment and see if toe or camber is off and creating the close tolerance. Also, check and see if rotor is shimmed properly to centralize it in caliper, might give you more mm. of clearance. Put wheel on and check clearance or put jack under lower arm and lower car to load arm, you might have more clearance as everything will be more level not at an angle.

 

Doesn't look right, does it ?

However, you could try taking a bit of metal off the wishbone using a grinder, if you don't have steering lock stops like those with steering boxes had, (bit don't go mad !!). Please note the outer bolt on the wishbone is not correct. These originally had a rounded head and very thin hexagon for a spanner to alleviate what I suspect Jaguar engineers found out in the 50s, and you found out in the 21st century, namely that there is a clearance problem. BTW, the discs are not normally shimmed to move them laterally, certainly not by Jaguar on assembly, although the calipers are shimmable to centralise them on the disc.

 

MK2's don't shim rotors, they shim caliper bracket to caliper. If R&P, one would think reducing the edge of the arm at that point might help.
