Why is this statement made in the Alldata site?
I need to separate these halves to hone the piston cyclinders.

NOTE : Do not under any conditions, remove or attempt to remove bolts securing halves of caliper together.

TIA
Peace

OK. This instruction is there to stop amateurs from separating the two halves and then using "Jo Noname" bolts to fix them together again. The bolts used are normally special high tensile material and designed to be used once and once only. If you have a source of bolts of the required specification, and have the torquing instructions then go ahead, otherwise leave alone. For calipers with an internal fluid passage across the two halves, there is normally also an 'O' ring seal and this should always be replaced at the same time. If it was me, I would try to find a place that does a service exchange for your calipers. I did this when rebuilding the rear subframe on an XJ6 around 1996.

 

Thanks Fraser,
I have seen a few posting that lean toward that.
But wanted to be sure, have no quames about replaceing spec bolts.
Thank you.

 

Should have finsihed my last posting.
What are the spec's for the required bolts?
I can get any bolt I require.
And what would the torgue be?
TIA

 

Hi Neil

I was going to hone my front calipers due to the amount of rust on the pistons. I was told by a guy who does Jag brakes under NO circumstances hone the calipers they WILL leak.

He advised me to use fine wet and dry sand paper wet and lightly go over the area that is effected.

I have seen Jaguar caliper bolts on eBay.
