they only way i understand it can be done properly and effectively is to drop the entire rear axle and mounting cage to be able to acess the brakes themselves in their entireity ,
a job i have to do next and im not looking forward to it! the problem always being today to find someone local garage wise who is competent and trustworthy with larger repair tasks like these
Ok, guys, if you look in the member area, there is a 700 page + workshop manual you can download free of charge which has, from memory, a lot of information on working on inboard brakes.
The problem with this one is there is no procedure for this task in any workshop manual
I myself am fortunate to own the Jaguar factory supplied four volume hardbacked edition of service workshop manuals these are the manuals that were issued to dealer workshop staff it doesent come any more comprehensive regarding a repair manual yet there is no where in those manuals that explain what procedure to use if you want to access your brakes yes it covers removing pads and discs handbrake cables pads and discs etc but no where does it say were to start or how to remove the mounting cage or rear axle in order to just get to the braking system on pre facelift cars I have to say it’s useless I. That regards everyone says you have to drop the axle and cage but no one seems to know how you go about that very task
I had one advisory on my last MOT. Pitted rear brake discs. I have an early facelift convertible, so it has the inboard rear brakes. Any info on best method to complete this repair would be appreciated. Work would be carried out by a very good mechanic but he has no expirience working on these brakes, so I would like to pass on any info I can get.
i have to say thats a new one on me Stephen, you cannot get at calipers, disc's and brake lines PROPERLY without dropping the axle down, ive spoken to EVERYONE knowledgeable with inboard jag brakes threy all without exception say the same "drop the axle out" i have the complete factory workshop 4 volume set for these cars its the same procedure in there!
Stephen is right, I've just done this, - a complete overhaul without removing the cage. You don't need any special tools just a bit of time and a good set of ramps.
The main problem can be how old the car is and how much use its had. i was lucky with this car as it was fairly low milage 1991.
The handbrake callipers slide down the back of the disk and the main callipers just drop out from below.
It took about an hour to remove the handbrake callipers and the same for the main brakes.
I took some photos along the way if that would be of interest.
HI have you tried you tack the bottom plate off remove handbrake cable off handbrake leaveresoff undo brake pipes remove brake pads by removing pins then pulling out pads then look at the disc brake there are holes in it to put socket on the calliper mounting bolt 1st remove locking wires on mounting bolt then remove bolts then remove callipers i have put new discs and callipers on my xjs cabreolet v12
Hi Stephen. Thanks for the info you have supplied. In your opinion, was it easier and less time consuming to replace the discs with the rear axle in place rather than dropping it. All info I have received other than yours suggest it is near impossible to undertake this task with it in place, so its good to know it can be done.
Again id have to say im aware of Mr Palm's experiences he wrote a PDF STYLE online book on his exploits of stripping and rebuilding his own car back in the mid 90's, he is or was an amateur XJ-S enthusiast as many of us in the u.k. are without wishing to sound rude again when attempting jobs like these practical experiences is where written owner information/advice all falls flat ! i personally need to remove complete rear calipers and disc's and replace rear brake lines and handbrake pads the only REAL way to do that is to completely drop the rear axle cage out of the car im afraid there is no other way round it "space" is the problem anyone who attempts to remove calipers and discs with the axle /cage unit it situ will find that you physically cannot SEE what you are doing when trying to replace mounting bolts on calipers for one thing you are literally working in the dark WITH LITTLE TO NO SPACE TO WORK IN
in the 23 years ive owned it ive had my own car up in the air on ramps countless times and considered this one from every angle!, another piece of advice i received was to cut a square hole in the boot floor as SOME people did with the E Type with the same inboard brake system !! something id never do cut my car up to gain access to the brakes practical experience discussing this one with main dealers and professional experienced Jaguar mechanics of long standing all say the same thing "drop the axle" its what Jaguar main dealers were doing back in the day in their own workshops to gain access to the REAR braking system
having worked in Main motor dealers all my life in the u.k. motor trade regarding this one im much more inclined to believe what im told by people who did this for a living back in the day at main dealer level than respectfully following one owners advice /experience in a book he wrote .again trying to convert that to a physical practical experience is going to see the same result you cannot make a square peg fit into a round hole with this one unfortunately , i think anyone who attempts disc and caliper /brake line removal and refitting is certainly going to come up against it with what ive discribed here i am going to have to go down the axle removal route there is no way round this one for what i need to do and thats changing complete discs, calipers, and brake lines its the way the manufacturer designed the inboard braking system on these cars that ensures that axle removal is the easiest practical way to gain complete access to these areas otherwise you will find you are fighting yourself in the dark with this one
from a personal point of view i have invested an awful lot of TIME and money in the last 24 years restoring my 1981 car its was a "mess" when i bought it back in the early 90's , ive spent in excess of £23,000 in 24 years restoring it back to to factory original condition, fortunately when i began many of the original body panels and trim were still available from Jaguar thats not the case today .1981 early production H.E. models were most definately "rot box's" and thats proberly why FEW exist in anything like good condition today ! apart from my own i struggle to find anyone else who owns a 1981 example H.E., So by vertue of the time and money ive already invested in this one i am over CAUTIOUS about attempting work like this thats not as per what the manufacturer themselves recommended , everything on my car has come out of a Jaguar bag or box the problem becomes today in finding someone experienced with working on cars like these from an earlier generation who can carry the work out correctly and competently at a realistic price after literally hundreds of hours working on the car as a whole id like to think" i know my way around an XJS " !, ive looked for alternative procedures for this task countless times and come up againstt a brick wall each time, taking the axle and cage out is a big job id rather NOT do that also ! but unfortunately as far as im concerned it is the only practical competent way to do the job properly
