Help! Urgent Tintop Brakes Question
James - 22/7/09 at 12:50 PM
Need some advice on this... sadly I think I know the answer! 
Have been borrowing my sister's Punto whilst my Golf is off the road.
The front brakes started grinding so I guessed the pads were low. Drove 24 low speed miles since (inc' 12m trip to factors for new pads) and in
that time one of the pads had shifted in the calliper and jammed on.
The disc is now quite grooved, the grooves are approx 0.5mm deep at their worst.
Worn Disc1
You can see where the disc has blued too.
So.... do I need to replace the discs? The other side of the disc is ok.
I suspect they need changing... I'm only loathe to do it as I need the car today, and have nothing to get to the factors with!
I spose I could fit the new pads, go and get the discs, then change the discs. But then I guess the new pads will have worn to the old disc pattern.
Thoughts? Ideas?
Thanks!,
James

the pads probably will wear to the grooves in the disc, but if they wear that quick in 24miles, when you get a new disc on, they should wear smooth
pretty quick again i should think

You know the answer, I think you're just hoping someone will persuade you otherwise. S'not gonna be me 
Give Andrew Page or whoever a ring, I'm sure they'll deliver...

yes to needing a new disk.

Get those discs changed. they shouldnt cost much from a motor factors

Definitely need new discs.
I would put the grinding pad back in just to go to the motor factors again and not risk damaging the new pads.
I think punto discs are pretty cheap - £8.50 each from shop 4 parts.

Actually whippy, it's not as bad as it looks regards that wear. I didn't take a pre-dismantle pic but the outer pad had actually jumped out
of place and was wedged in against the bell. Hence why the rust has been rubbed off there.
The disc is about 10mm thick still.
Cheers,
James

One of the reasons worn discs are dangerous is a worn pad can slip out and jam the wheel solid without warning.

new discs buddy, new discs

That's f**ked, new ones will be about £15 a pair. Get them changed and fit new pads at the same time and it will pull up evenly with no judder

What's wrong with ya pushbike or the bus to get down the factors....?

Guess that's what happened and why the pad's slipped!
Anyway, new pads are waiting for me at the factors near my Mum's. She's bringing them over to me.
I can't cycle there as apart from only having my girlfriend's bike here, I've rather badly twisted my ankle kickboxing!
As for public transport.... hmmm, well it'd be 2 or 3 buses or 2 trains and a bus!
£25inc for the own brand discs. Hopefully my sister will pay as it's her bloomin car!
Slightly annoyed as it was only MOT'd 500 ago and no mention of worn discs/pads.
Thanks for the advice everyone. LB is the greatest!
Cheers,
James

Fiat calipers are good a seizing up as well. May be cntributing to scrapping your discs. Worth checking.

Well I think that as BT said, the reason the pad had slipped was the combination on nothing left of the pad:
Worn Pad Linky
And a somewhat less than optimum disc! Somewhat smaller than it should it I guess!
New vs. old disc Linky
Maybe my sister's just trying to garantee her inheritance!
Thanks all!
James
