Brake disc wear - how much is too much?

[rustic]

Your posts have helped me enormously, Rustic. I know we don't know each other personally, but you've helped me directly through your contributions more than you'll ever know! And it's very, very much appreciated!!! I just wanted you to know that, mate. I'm Stu in real life, by the way :thumb2

Thanks for that Stu, it means a lot. :thumb2
I have only met a few members on this site myself, through meeting up for the odd part or two, and then not all for the Maverick.
I don"t know what it is about this site and it's members, why we have become a very close family, I assume it's because we are like minded, but from different backgrounds, from all walks of life, because of that we all have our strengths and weaknesses. I tend to think things through, often too much, searching the internet constantly for missing knowledge, I am a logical person, a cross between Mr Spock and Scotty, I love the internet, I just wish I was born 20 years later, to have enjoyed it for longer.
I am not too good with the big hammer stuff, like welding, but I do own my own small mig welder, grinder and a selection of small, medium and even two sizes of sledge hammers.
I love helping people, probably a reason why my later part of my career steered me towards teaching maths to 11-16 year olds, as I got fed up with the unreliability of the job prospects in Industry. My first career was electronic engineering, designing instrumentation and control systems. Helping and supporting young people is very rewarding, as Jim of Jim's Terrano will tell you. Now this is where a person can make a real difference to so many. Sorry this sounds more like an obituary lol but I could write a lot more. I tend to be the one that all the family call on to sort things that go wrong, I spend hours fixing an item of my children, and now our grandchildren, even though the item often only costs a pound or two lol... a true sign of an engineer.:lol
I fix a few things for neighbours too, but I am shelving most of that to spend more time with my family. My son, wife, and their baby daughter are flying in from Bahrain later this week, to stay with us for Christmas, and New Year, we haven't seen them in the flesh for 6 months or more, thank goodness for Skype.
Looking forward to that.:thumb2 So I might not be on as long as I am now.
Only 4 hours a day instead of 6 lol...:lol:lol Actually that's probably an underestimate, If the TV is on, then so is my ipad, lol...
I tend to get tired early now, due to the hormone medication and our son has bought us a pallet of holly trees to fill in a gap or two in the hedge, I said do they come with "free fit" :lol:lol
Anyway, a very Merry Christmas and a Happy New Year to our members and visitors alike.

Right, that's one side done. Do the other tomorrow.

Took me around 4 hours but there was quite a bit of faffing around. But still I'm in no rush

Thanks for all the help.

While I was there I whipped out the bearings, gave a clean and prepacked them. So in the manual it SaYS general purpose clgi2. So that's what I used but now I'm having a panic!

The stuff I used was clgi2 multipurpose lithium grease good from -30 to 130 degrees c. Good for bearings, bushes and something else with high loads and pressure ( roughly translated from the spanish ) For the life of me I can't think how hot bearings get but they must get at least warm. Is the 130 degrees OK?

Do not worry your grease is fine, did you remember to pre load the bearing? Rick

Ermmmmm...not 100% sure. I tightened the nut as tight as I could get it with a hammer and screwdriver, so it squeezed onto the stub, spun the wheel around a couple of times, undid the nut, spun the wheel, tightened the nut up tight again then undid it so there was just a slight nip and the locking nut screws could fit in place.

Does that sound about right? I saw in the manual they had springs and things but I ain't got any of that stuff.

not quite, taper roller bearings have to have a pre load to run correctly this means do it up till no play at all then a further 1/8 turn if the locking screws do not quite line up turn tighter till they do, it will only be a small amount but do not turn back you may lose the pre load and as said for a taper this is bad, Rick

Cheers for that Rick, I'll whip the wheel and hub off and tighten up. I was just a bit worried about over tightening after reading the manual which I interpreted as tighten up then slacken off the nut.

But with hindsight you've really got to go some with that hammer to do that.

I couldn't feel any play when I put the wheel on and rocked it top to bottom. Side to side had a bit but when I looked that was from the steering.

I'm trying to think if i can do that with the caliper on or not. Guess I'll find out tomorrow.

yes can be done with caliper on, the secret is tighten till no play with wheel on then around one and a half holes more on the nut, Rick

That's it done!

So, pads, discs, crank pulley, crank pulley seal and winter service!

Thank you all for your advice and help.

Only rear brakes to check now. What's the best way to jack up the back ( Oo er Mrs )?

From the axle and then use axle stands and chock the other 3 wheels? I've done this before but have just had a complete brain fade.,.
