Mmmm kay....don't get me wrong here. I'm not complaining about my car, the company that made it, or the good folks that put it together.
What I am complaining about though is the darn engineers that actually thought their stinkin' disigns would work.
Stinkin' design number one has already been mostly covered in rant #1..that being the hydrolic brake lines and lack of a way to properly bleed them (an issue that I'm still having troubles with after a week and 3 good bleeds and about a half gallon of brake fluid so far. Gets a little better each time.) In rant #1, I said there weren't nothing wrong with the drum brakes. Well, I guess I was wrong...which brings me to rant #2.
Of course, there's nothing wrong with drum brakes. I was right when I said that. But Jaguar XK120 drum brakes suck! The rear drums are OK...simple single piston that pushes the manually adjusted shoes into the the drum. Thats all fine and good (except that you can't bleed the cylinder)....but the problem(s) lie in the front. OK...there are two pistons per wheel (one per brake shoe), which is fine. But...there is this self adjusting setup that looks to me like it belongs on a kids doll stroller (not safe enough for an actual baby stroller). Two stinkin' little arms with little sixteenth inch ratchet teeth, and dumb little ratchet springs that go over them...and some ridiculous shims and washers to hold that all in place. Granted, I suppose it works when all the parts are new and you never see a gravel road....but....
Well...one of the last times I drove that car last summer was over about 20 miles of gravel road. When I got home, I had a somewhat mysterious squeak in one of the front brakes. No biggie I thought...just a little piece of dust. Well...after not being able to fully bleed the brakes after the new master cylinder, I decided to pull the drums today and have a look see...lo and behold...one of the front brakes had pretty much disassembled itself. Oh...the brake shoes were still in place, and were still working, but the adjustment bits had fallen off, and were subsequently not adjusting worth a darn! Luckily, I found all the pieces and re-assembled it with better cotter pins (that was the culprit...two sheared off cotter pins). I used some nails this time. I reckon they won't break as easily.
So anyhow, the brakes are working as good as they can be expected to...with the exception of air in the lines. But I can stop the car without pumping the brakes again...which means I'm almost on the road...except....
Stupid design #3. Lower ball joints.
If you've ever had a lower ball joint fail in any type of car, you probably know that it sucks. The ball comes out of the top of its socket, and the car falls on its lower A-arm, and you lose control of one of the wheels...causing you to die a horrible death unless you happen to be going less than 20mph.....which fortunately was the case both times it happened to me.
No...that didn't happen in the Jag, thank God. But, having been through the experience of losing a ball joint, and knowing that the lowers in the Jag were a little loose, I opted to get some new ones....
Now we all know that the whole weight of the car (or at least a quarter of it) hangs off the ball joints. That weight isn't supported by the ball joint....the car hangs off those suckers. Which, of course, means that the weight of the car is suspended by the top of the actual ball, which is held in place by the socket. So...if the ball joint breaks, where does it separate??? At the top of the socket where its all worn out from carrying all that weight for years. Right? Of course.
But if you want to rebuild your XK120 ball joint, what do you get? You get the lower part of the socket, and a new ball. The top part of the socket that carries all the load and wear is a big chunk of the car, and with no replaceable ball joint socket. Granted, replacing the lower half of the socket will keep it all nice and snug, but thats all. Its a stupid design.
I guess the folks a Jaguar simply put all their efforts into making a cheap car that looked great, and had one of the best engines ever created under the hood. Still amazes me that folks still are tearing out that wonderful masterpeice of a motor and slopping V-8s under bonnets...when the real problems of the cars are almost everything EXCEPT the engine!
Like I said...I ain't mad at my car. Its obviously the most beautiful thing I've ever driven (duh...what could be prettier than a XK120 coupe), but there sure were some problems in the engineering department.
I'll keep y'all posted when I find more....or more like...I'll keep y'all posted next time I'm into another stupid design again...and again...
Happy motoring all...
I will be soon.
