Break Disk Damage and Odd Tyre Wear

[Antsmash]

Hello =)

My 2003 VY Exec. has a couple problems. Two problems...

1) Was driving a few days ago then noticed this horrible noise coming from the back right wheel. Loud grinding noice. It went away, then came back over the next few days. Had a look at the disk and some very serious wear on the outside of the disk, and what appears to be none on the rest.

Just tried to get tyre off but bolts have been over tightened, some of the mag bolts seem to be different threads and one won't come off. So going to have to take it to a tyre shop.

What do you think would cause this damage?




2) I have some very cheap tyres. Asked a good 5 people +, nobody knew what they were. So do plan on replacing them. But what would cause them to wear like this. Lots of tred apart from the far far, inside corner where there's belt showing. Side with faulty disk is the worst

Right Side (Worst)



Left Side



Fronts are wearing evenly. Is this just how cheap tyre wear, or is there something funky going on in back end =)


Thanks for the help!

Tyre wear could be due to a camber issue.
1. Is ure car lowered?
2. Are your bushes ####ed?

Brake disc wear
1.How much meat is left on your brake pads.(The floating section of your caliper could be seized, resulting in uneven wear one your pads.)
2.Is your brake caliper tight.(Mounting bolts could have come loose.)

the tyres are probobly camber ware

brakes could need some new fluid pumped thru em, new pads, new disks... dunno why its only that one though

[Antsmash]

It's not massively lowered.. Some shots here - My VY Exec with Kit and Saying Hello :)

We tried to loosen the caliper a bit to see if anything had moved, or pad was munted etc. But could get bold undone without take wheel off was that tight, so calipers seem fine.

The rest of the disks are fine, and the car stops quite well. So I'm not sure what caused it, very interested to find out.

Looking at the tyres they're not on a massive camber, but that could be reason.

Firstly you've managed to utilise 99.999% of your pads and now its the metal on metal thing.. The tyre wear is the norm sadly (yours seems a little more excessive however) and if you leave it long enough your pictures are the proof of the pudding.. One thing you may have to do is sort your rear end via camber kit or the like.. Best you get the pro's to sort it as it's really something you can't do at home without the right equipment. I'm hardly an egg spurt but clearly you need to see a tyre bloke

FFS maintain your car! Your pads are metal on metal and your tyres were due for replacement several thousand km ago. Might want to head back to school and learn how to spell. It's "brake" ffs!

Thanks Caff that helps =)

Easy reaper, I've owned the car for two months, and have got money set aside for new tyres, but only just realized far inside of rear had belt showing.

You bought a car and didn't check it for basic safety items before you drove it??? This is beyond just a little un-roadworthy on the tyres. It is a danger to you and everybody else on the road anywhere near you.

VY V6 with Clubsport kit with thrashed out rear tyres.....wow. Hope you've got plenty of money set aside to fix everything else that's about to break on the car.

[Antsmash]

It was a Cop Car for it's whole life but one of it's years. I know it's been well serviced, minus that one year of who knows. Was serviced as I purchased from a dealer. I'm not sure how it got a Warrant with those tyres, I'm pretty sure I haven't done that in two months. She runs like a dream, minus the tyres which I knew I would be replacing with decent ones anyway. Appreciate the input.

Breaks worked well up until now. I assumed the pads were good, but did plan to check them soon with service. So hopefully I'll see what happened tomorrow.

Err don't know about you but normal people get a car thoroughly checked over when they buy o.O

[Antsmash]

I checked the tyres for tred. But obviously I didn't feel all the way to the inside of that ONE tyre. As for this disk problem i'll be interested to see what the cause of it was..

[acarmody]

Its called pad are FUBAR.

Both tyres are rooted. Rotor is ####ed because you let the pad's get too low.

The cause of the disk problem is that the pad has run out of friction material. All of the tyres pictured above are un-roadworthy and dangerous. They should be replaced immediately. Can tell that from your pics!

This car should not be driven till those two items are rectified. I also strongly suggest a comprehensive check by a qualified mechanic of the whole car immediately.

Thanks for the suggestion reaper, I'm currently writing to the dealer about this as well. But have had brakes checked, new pads on rear, new set of disks on rear, and 4x 18" Bridgestone Potenza. I have a mechanic doing a full check next week.

Appreciate everyones advice =)

Will make sure to check alignments etc. Still curious as to why tyres wore like that on far edge.

[ashbox]

its called your camber is up shit creek...

[Antsmash]

Is there a easy way to see how "Up shit creek" it is.

Take it to a tyre joint and they tell you what camber it's on when you get the alignment done.

[Kingston_99]

you need a 4 bush camber kit, also to replace all your brake pads and that one rooted brake rotor. may as well upgrade them all to slotted rotors while your at it.

Camber. As has been said to you many times. Camber is when the wheel is on an angle if you will, in your case, your tyre does not have even contact with the ground, the inside has much more pressure on it causing it to wear unevenly.

Ill put money on that being the rear right wheel (the one with the belts showing). Its pretty clear someone has been doing single pegger burnouts, either you, or the previous owner has clearly treated this car like shit.

At very least, you need 4 new tyres, 1 new disc (putting money on 4), 1 set of brake pads (putting money on 2), a wheel allignment and probably a camber kit and whatever else is wrong with the car.

I havn't had a problem with camber. Wasn't this fixed by Holden before the introduction of VX or VY?

All IRS Commodores have it, even VE's to some extent. They got progressively better as far as uneven tyre wear went as time went on. To make matters worse, some cars had bad tyre wear whilst others were fine within the same model.

OK, cheers, Reaper, I hope mine stay good then, as I havn't had an uneven tyre wear problem yet.
I know that just looking at the back of some VT's, the problem is obvious and looks shocking.
