Portfolio Alcon brakes installation question
#41
Thanks again for all of your help. The installation went well and the brakes function brilliantly.
Now I am ready to do the park brakes. I did find a set of used ones from an Aston, they should be an exact fit, correct? However I have not yet located the needed brackets.
EDIT: meant to ask, for the park brakes & brackets, do I need to order all new bolts as noted in your parts list (caliper to bracket and bracket to hub & tierod) or will I be reusing any?

For the bolts you'd need one longer one for each rear hub as one has to pass through the bracket into the wheel bearing, bracket thickness approx 5mm. Standard bolt easily found though.
The tie rod bolt is as standard fitted with the bolt head downwards and the nut on the bottom.
With the Alcon bracket fitted the bolt is turned upside down and put through the tie rod and hub from the bottom. And the park brake caliper bracket is threaded to accept this.
I used thread lock on these bolts. ( torque spec in the manual)
Hope this helps

Do you have a picture of the calipers? If you also know the bolt spacing I could confirm. So far as I'm aware the brackets are NLA from jaguar but TL jaguar sell copies as they've tooled up to make these. ( I do have a spare set of these)

I ordered all new bolts and the brackets from Jaguar but it may be a few weeks before they arrive from the UK.
I assume you meant Tom Lenthall? If I can get the brackets faster and less costly, I would be interested. Thank you very much!

One thing to check is that jaguar actually have the brackets. I was told that one side is in stock and the other is on back order. Considering they are cast iron they'll be on back order forever.... if you can't get them from jaguar let me know I could sell my TL brackets to you...

That's a shame to hear. He did say he was moving away from them but as you've found out there's a wide range of pads available and floating discs to go to a full race set up. Should you so wish.

Weird thing is only one of the brackets showed up today, C2P14734, though they claim the other is in transit from Honeybourne.

I googled Alcon seized calipers and saw some fairly horrific pics and read some threads about others' experiences, particularly Evos which outside the US were spec'd with the same calipers, but not sure how they let them get to that condition.

It looks to me that you need to remove the whole hub carrier in one piece off the axle and wishbones, then you can get those four bolts out...

At this point I'd agree with Cambo on the next steps, when I did it I bolted the brackets to the hubs off the car, as I'd changed the wheel bearings at the same time, but even removing the hub nut and then the tie rod bolt in combination with the upper ball joint should allow enough movement to get the axle splines out far enough to remove the bolt.
Hope this helps
