Question Handbrake Calipers Rebuild

I am having a hard time sourcing replacement handbrake callipers or finding a place in Canada or US that refurbishes. Any recommendations?
What I have are so terribly rusted that my preference is to simply replace them rather than overhaul them myself.
It would seem that there are no aftermarket compatible callipers and these are a rare find for fully refurbished.

Not that hard to source the parts.


1. Used and serviceable or used as cores for rebuild. Perhaps NOS pads as well. David Boger at Everydayxj. South of you in the Carolinas. I never remember which one!


2. Rock Auto in the USA can supply pads if needed and David doesn't have a suitable fix.


2. Search the Archives in XJS, same system. Greg posted a great write up on making the system better.

I've never seen refurbished handbrake calipers for sale.

Rebuilding or refurbishing a handbrake caliper is nothing more than ......

1) Disassembly (a couple screws to remove and a pin to drive out)

2) Cleaning out gunk and crusty dirt

3) Re-greasing the mechanism

4) Reassembly



Cheers
DD


PS- I'm assuming we're talking about the handbrake calipers used on the inboard brake cars....A Series I-II-III XJ6/12, for example

check with SNG Barrat USA store

SNG Barratt - The Ultimate Jaguar Parts Specialist


if your car has independent rear suspension, (IRS) some have adapted Series 3 XJ-6 front and rear calipers to classic S type / 420 / 420-G / MK-10 / E type.

As Carl says, David Boger should be able to supply you with some used calipers that are not rusty.

But.....

Even rusted examples can likely be brought back to life. After disassembly the parts (there are only a few) can be wire-wheeled to remove rust.

Agree, I've done a lot of time on the wire wheel and at the bead blaster.


Still have my "heavy duty' wire wheel. Somewhere in my travels, I came on a power head from a Craftsman radial arm saw. Locked in it's travel path, so useless as a saw!!


Lots of power in the motor, though. Accepted a big wire wheel in lieu of the blade perfectly. And, just the right size to clamp on to the chunk of "I" beam attached to my "bash/weld" cart!!

Thank you for the help and direction folks. I have emailed David Boger and looked at the parts supplier SNG Barrat.

Refurbishing is a last resort for me on these. The rust has eaten away a few of the components to the point of no restore. Replacing some parts and restoring others is plausible... but the hours devoted to the project I am not a fan of (if avoidable); in near 30 years of driving I have only used a handbrake once or twice on an automatic transmission. I actually debated omitting the entire system!

Robert:


I'm with you on the last part. Except, early on in my decades of driving critters ! Lousy mechanical brakes in most. Apply lots of pressure, foot and hands to deter the critter's
forward motion.


As of now, the hand brake action on my Jaguar is zilch. On Jeep, used by daughter when loaned to her. Seldom if ever, by me.


Should I. Yes, I gotta admit.


Don't want to retell the Jag's near disaster because I thought the hand brake was "fixed".


71 years of "driving" here....


So, if you can, fix it...

Once you get the handbrakes working (assuming you don't just get rid of 'em!) it is important to use them regularly. *Lack* of use is what kills 'em !

Optimally, when parking any car, you'd first set the handbrake and then put the transmission in "P". Thus the brake holds the car, leaving the parking pawl in the transmission as the backup. But, as we all know, not many people do so.

Once, in my misspent youth, I was driving around a mountain town where I wasn't supposed to be, and parked on a street with a steep grade. As was my habit I merely stuck the car in P and left it. It bounced back a bit but I had my mind was on other things and gave it no thought.

When I tried to drive away though, there was So much pressure on the parking pawl I couldn't get it out of PARK without Heroic effort! In fact, I was afraid I would bend the column linkage and I'm surprised I didn't!

Worse than that was if I had to call for help and my parents learned I was there. That gave me *Motivation.*

It also taught me a lesson that only Fear etches into the psyche;
Always put on the Park Brake on FIRST!

Thank you

Don't know about you but when I try explaining this to people (my kids, for example) they look at me as though I had just landed from outer space

When I try to explain Anything car related to Anyone they look at me like I came from outer space.

Maybe that's because I don't have a folder of pictures to speak for me;
1 Picture=1000 words and all that........

I'll try to remember to capture and share some before and after photos. Replacement will be fairly easy now, with no rebuild/referbishing.

Service brake "loaded rebuilt calipers" definitely, at least at one time. My car has a pair. Other sources as well. Similar pricing. But no core needed for the Rock Auto product cinched the deal.


Anyone want a dirty pair that leak?


As to the hand brake calipers, I've my doubts as to their stocking them. I don't know.
Easy to check though.


As to pads for the hand brake, yes, at the time, I got mine.

Ya, Rockauto does not have handbreak calipers. Was one of the first places I checked.

I should be good with the ones from everydayxj. I'll just have to source 1-2 pads I think; will know when they get here.

Incidentally, I spent some time tearing appart the ones I have to see what could be salvaged. Most parts disintegrated so I stopped waiting my time on them.
