Yesterday afternoon I had a bash at sorting out the ball joints which there was some play in, the worst of which was the one between the steering knuckle and the drag link. Didn't take much work to find that!

It turned out though that there was absolutely nothing wrong with the ball joint...The nut just hadn't been tightened up properly, the clonk was the taper moving against the seat rather than actual play in the joint. I got at least an additional two or three turns on it...Then surprise surprise, there was no play in there any more. Having a closer look revealed that they were all like that with the exception of the one I'd already changed.
Back to today - I wanted to finish up the work on the brakes. This meant making the adjustment to the brake yoke assembly to account for the different rest position on the new master cylinder. The easiest solution to this I'd figured was to drill a new hole in the yoke slightly further back, and slightly further up to provide a little additional mechanical advantage to account for the fact that the new master cylinder has a slightly wider bore (which in theory would make the brakes heavier to operate), though the other reason for moving upward slightly was to ensure that I stay well clear of the original pivot point, the last thing I wanted was to have a drill slip cause damage to that - plus one of my goals with pretty much any of the improvements or modifications I've been doing should all be things which can be reversed in the future should I/any future owners want to. A blob of weld and a bit of paint will be all that's needed to get rid of this hole if someone was so inclined.
Before I could do that though I needed to get the yoke detached from the car (as the support frame is in the way of where I'd be wanting to drill). You don't actually need to remove the steering tie rod, indicator wiring etc - just these two bolts (one of which required a LOT of effort to initially crack off).
With these out there's enough reach on the wiring and flex in the steering tie rod ball joints to rest the yoke against the seat to work on it.
I actually did this the right way for a change, using a centre punch, small pilot drill and progressively drilling out to 8mm (which is pretty much spot on what the original hole was measured at).
Tidying up from doing this and getting ready to reassemble things, I then dropped the pin from the clevis and lost it.
Or rather I *thought* I had dropped the pin and lost it.
Can you see it?
How about now I've turned the flash on?
I wasted the best part of half an hour hunting for that blighter...which I had of course actually put back exactly where I meant to, right next to where I was working.
On the plus side, while crawling around on my hands and knees I *did* find the similar pin which I lost from the gear linkage back when I did the engine swap!
So that's a bonus, I'll get that cleaned up and refitted next time I've got the rear service hatch out.
Now I had fully expected getting things back together to be a pain. Having moved the pin forward in the yoke meant that there was no longer clearance to get it into the hole it needed to go into. Eventually a combination of a bit of levering to flex the yoke to one side and loosening the master cylinder off got it in there. It was a bit of a faff, but I knew that going in. This isn't something that you're going to need to remove all that often (hopefully!) so I'm not too bothered that it's a bit fiddly.
With things reassembled I was rewarded by a much more reasonable feeling brake, and after another thorough bleeding session (turns out there was still a lot of air trapped in the front circuit) and we were rewarded with this amount of travel.
Brakes fully released:
Brakes firmly applied:
That looks (and feels) about perfect to me. I can get about another 3/4" if I really hang on it.
I think we're now at the point where I need to find out if this whole messing around has been a gigantic waste of time or if my brakes still work (I'd not complain if they're better too!).
I need to run a couple of errands tomorrow, if it's not tipping it down with rain I will probably treat that as my test run.
So...What's been done since she was last out?
[] Distributor condenser remotely mounted and remote start switch fitted. Can't 100% remember if that was actually done before or after I started pulling things to bits now!
[] All brakes cleaned, pads de-glazed and adjusted.
[] Offside rear wheel cylinder replaced (due to seized bleed nipple).
[] Split circuit brake master cylinder (Triumph Spitfire) fitted, requiring slight modification of yoke.
[] Rear brake flexible lines replaced.
[] Driver's seat frame bolted to rear runner to stop it wobbling.
[] Got rid of a few kg of flashband from the rear service hatch.
[] Sealed the bungs around both the heater/choke control cables and gear linkage.
[] Cylinder head temperature gauge installed.
[] Front mud guard removed and straightened out (still need to re-fit that).
[] Dayco HP2020 CVT belt fitted.
Aside from a bit of miscellaneous wiring tidying I think that's everything...Hopefully I've not made things worse than they started!
Clear a few bits and pieces out of the way then we should be all set for a test drive tomorrow.
Determined to get this sorted out before I get...sidetracked...by the arrival of another vehicle later in the week.
