Hi Guys

I've got a bit mixed up with the Caliper Bolts, as to what Bolt goes where.




I know the Ball Joint goes in the bottom hole of this Steering Arm but I've got a bit lost after that.


Have I got the right bolts in the Top and Middle Holes (They have holes for wires)

Not sure about the Bottom one of the 3 Bolts in the Photo

Please can you help.

 

Itis rather aimple. Put the arm on and hold the calper in place. The area where the caliper and the steering arm are mounted to the upright, requires the long bolt with holes. The smaller one with a hole is miunted to the other caliper hole. The last oneholds the steering arm to the upright.

 

OB, Just to be 100% sure:
The bolt without the holes for the lockwire is the topmost one that goes through the top end of the steering arm and into the upright.


This leaves the two with the lockwire holes. The shorter of the two is the highest one and goes through the caliper and into the upright.


This leaves the longest one that goes through the arm, then the caliper and then into the upright. This is the one that has to be set up with the shim between the arm and the caliper. The exact procedure for which I outlined for someone in a post a month or two back.


In your photo you have the wrong one shoved through the top hole of the arm. It should be the one you show on its own without the lockwire holes.

Hi Greg

Thanks but one of the things that threw me was the Top bolt into the Arm that didn't seem to have much of a Shoulder on it.

Have I got it right now (Lol)



XJS Caliper Bolt Positions

In the Photo the Bolts should be facing round the other way.

 

Those calipers look nice! What colour is that? A bronze or so? Looks really tasteful!

 

Hi Daim

Apart from the fact that the bolts are going through the caliper and arm the wrong way, and assuming the topmost bolt has NOT got the lockwire holes (I cannot see the bolt heads in the snap), yes!

Hi Greg

Thanks, I've got it now just got to turn the Bolts round.

 

Sorry to intrude but, No. That steering arm is wrong. I think you have LH caliper with a RH steering arm.

 

Hi Baxtor

You could be right!

But I have got the other one in the Garage, as at the time I was more focused on what Bolt goes where.

Anyway well spotted as I hadn't noticed until you mentioned it.

 

Just pop a wheel off your other car and compare. You have a nice 3D model ready to copy

 

Good idea!

 

Like this OB:

And the bleed nipples at the top!!

Hi Greg

Does this look ok to you?

The Steering Arm is only being trial fitted with none of the bolts done up tight.
But is it the Long Bolt with the holes for the Wire, the one that needs the Shims on?
and if so which side of the Caliper do they go?

Between The Steering Arm and The Caliper or The Caliper and The Strut?





Is it the Long Bolt in the Pic that has the Shims?

That photo is correct for the RHS. The caliper is not there yet! But it is obvious how to fit it, as with the nipple at the top there is only one way that it will fit.


If you imagine the caliper was there, the LONG bottom-most bolt would go as follows:

1. Through the arm as in the photo
2. Then the shim
3. Then the caliper's bottom-most hole
4. Then the bolt goes into the threaded hole in the upright

To find out what size of shim you need:
Bolt the arm topmost hole to the upright,
Fit the top caliper bolt straight through the caliper into the upright threaded hole
LOOSELY fit the long bolt through arm, caliper and into the upright; but DO NOT tighten it, (it just ensures the caliper and arm are properly located)
TIGHTEN the top bolt through the top of the arm and the top caliper bolt into the upright. Not stupid tight, but well nipped up


Now, take you feeler gauge and find out the gauge thickness of the a space between the ARM and the caliper on the bottom bolt's shaft. Normally this is around 10 to 20 thou. Get a shim of this thickness and then with much cursing and difficulty, fit it!
Cheers

Hi Greg

I think I'm getting the hang of it now.

Thanks for your help.
