The bolt that acts as a cover for the adjuster screw on the rear callipers has had the head stripped/rounded (not by me). Does anyone have the measurements for this bolt? ie m8x1.25x15 or what ever,
It was a rough night on the turps so sorry if the question sounds messed up.

I thought I might have one but sorry its gone. I suspect it will be a hard bolt to match because of an unusual head size meaning second hand or holden only. If you can get the old one out with mole grips you could file new flats onto it. If normal methods dont work try soldering a bar with a slot on top of the bolt and useing a screwdriver to undo You could also try epoxy instead of solder to keep the heat down

Thanks Alan,
Yea. i cant see any reason they use the low profile head on that screw. but i plan on just getting a plain screw with the correct pitch and TPI and modding to fit, maybe willes and adams will have 1... lol.. yes sir id like 1... yes 1 screw.
I had started to make an attempt of using vise-grips to remove it, but i have a gut feeling that if i do it will make it unusable. and since fluid is leaking past the adjuster i cant not have that cap on there.

Hi.Bolt is m10x 1.5.If you give the existing one a smack on the head with a smallish hammer the copper gasket under it may compress a little which effectively loosens the bolt.It also flattens the burrs allowing the spanner to grip better.The less shamfer on the ring spanner or socket the better.You could even grind or file a squarer edge on the spanner so it will grip more of the hex.
Hope you can understand all that and it helps.
Regards,Harry.

Harry has a herd of bighorns like mine which has the same brakes as yours. Hes also in the nut and bolt trade so I would trust this info

If you cant get a grip on the head, you could cut a slot across the head of the bolt with a cutting disc on a grinder and try a impact driver.

Its brass and quite thin. Not sure if I would put a grinder near it but a gentle saw blade or file might work the same way. It shouldnt be that tight

Remember the copper washer and it will be ok but brass or stainless would be better if you can get it

I had the exact same problem today, I can't see why Mr Isuzu used a low profile head either, just a total PITA.
Both bolts on my MU look original yet only the washers are brass, the bolts them selves are just steel on mine.
I ended up using an impact wrench on one of mine to get it off then a hacksaw to put a slot in. I slotted both bolts even though only one had a problem, just in case. I have had both off in the past but last time I did one side and my brother did the other. I don't remember who did which side, so of cause I'm going to blame my brother ;D ;D

Did my brakes a few weeks ago and mine where steel.
Mr Isuzu thought about it when he made these bolts, he thought that heaps of people will have trouble undoing them, stuffing them, then buy more because they didn't think about replacing them with normal bolts, hence he gets more sales = more money!!!
