Hilux MK6 Chassis and Rear Tub

Brakes set, the micrometer worked a treat.

Everything crossed for the MOT tomorrow

Handbrake cable adjusted (although probably so stretched it needs renewing as it's almost bottomed out).

Did an additional bleed just to be extra sure and got a few more bubbles, I can't get the load sensing proportioning valve nipple out (I have a replacement and everything, but it's corroded from 10mm to 7mm hex) to do the bleed there, but it's behaving fine so we are probably good.

Hopefully we are all good.

It passed!

The tester gave me the comment "Looked like it's given you a good bit of work at the back there youth!" and we had a discussion of how appalling it was that my (admittedly cheap aftermarket) CV boot was cracking after only 10 months service.

Weirdly it's just one of the four that's doing it, and they all went on together...

New spiral cable in, airbag light off, horn working, tested with the diagnostic software, happy days.

On disassembly of the old one to understand what went wrong, the ribbon cable inside had shaken loose of the spring loaded clip which holds it to the output connectors. I think me giving the steering wheel a firm yank to free it from the splines may have jiggled it just enough to make it fall out.

Everything now works, the handbrake is still not quite right, based on the current brake pedal travel, it feels like it does when they're quite worn so I probably left too much shoe clearance doing it by eye.

I don't want to overdo things tightening them by feel, so might have to pop the wheels back off tomorrow and use the 9"-12" micrometers to set the shoe position (I don't have calipers big enough) giving the Toyota recommended 0.6mm of clearance from the 295mm internal diameter of the brand new drums. I guess that's a reading of 590 thou with the 11"-12" anvil fitted.

Just a thought, but Hilux are known for hand break issues an often the pivot point on top of the axle needs freeing up an lubricating, worth a look if you aint already.

Already looked at it and the cable connections when I was messing with the secondary adjustment turnbuckle underneath, it still moves freely.

Based on the fact that the shoe clearance is dead nuts on, the lever and equaliser move freely, and I'm bottoming out both adjusters, it's got to be cable stretch.

I guess I will sort it out when I get back from my next long trip, for now it works and that's adequate.

The advisory on the last D2 MOT was "chassis is covered in underseal"

I thought "thank **** for underseal then"
