Brake discs warped AGAIN !!!!!!!

Either way its garages fault then...

Way I look at it, I go into garage telling them brakes are juddering, they use they're expertise and recommend what needs doing.

If then afterwards its a case of either:-

or

I would say its their cost to sort it out...

Hmmm. I am tempted if things dont get fixed this time to demand a refund and go to the Kia dealer and make sure I get genuine Kia pads and disks....

At least that way I can be sure that these things are not the issue. I can then also shout at the Kia dealer if things still dont work out...

No, put the hand brake on and put it in Neutral. Just as you would with a manual transmission.

No, I also drive automatics. See that letter "N", that's neutral that is.

Bollocks.

I think you've identified why your disks are warping.

They're cars built to the lowest price possible.

Mrcheerful ("Mrcheerful" ) gurgled happily, sounding much like they were saying:

I strongly suspect it's the harder compounds in modern pads wearing disks faster - and because they're required more often, they're made down to a price. I know when I got my first CX in the early '90s a pair of (vented) disks was _bloody_ expensive - about the same as three tanks of fuel, IIRC. The pattern (vented) disks I got for the Saab were about £20 each.

When I was young it was almost unheard of to change discs in the life of the car, now it can be every other service. I agree the price has plumetted.

I agree. I don't recall disks or drums ever being an issue back in the 70s and 80s. My 1983 Astra GTE racked up 47000 miles without the disks being appreciably worn but on my current Focus they were close to the 2mm wear limit at 30,000 miles. Mind you I think a wear limit that low is taking the piss a bit so I just skimmed them on the lathe and slapped them back on when the pads got changed. They'll do for two sets of pads I think not just one.

The single front steel disk on my 1976 Honda 550 doesn't actually have any visible or measurable wear at all after over 30k miles. It's literally like new without even a hint of a wear lip. It's also presumably a stainless steel of some sort because it has no rust either. I'm sure I've put pads in there at some time but it seems only the pads wear and the disk remains untouched. Why modern cars are so different I couldn't say. Car disks have always been made of cast iron of some sort so it must be the pads that have changed.

Dave Baker ("Dave Baker" ) gurgled happily, sounding much like they were saying:

Hmph. 1mm wear allowed on the Saab...

Mine has a "Hold" mode that holds the car on its service brakes when stopped and in drive or neutral. Not had any problem with my brakes. I think some cars are just crap on brakes. The Volvo was, so I switched from OE discs/pads (life

Thats probably the best suggestion so far .

Isn't that "Just about anything as long as it's not made in Korea."?

The disks for my DS were only about =A330 each. The pads, on the other hand, cost over a hundred.

Being honest, and putting brand snobbery etc aside, having used and abused a Daewoo for a while, I think there's nothing fundamentally wrong with cheap cars if you accept that that is what they are. Kia / Hyundai / Daewoo / Proton etc are actually not as bad as you'd hope they were, just don't expect anything to be over-engineered on them, like braking capacities.

Hmm well after the experience of a Hyundai Stellar and a Daewoo Nubira I took to writing "No Daewoo, No Hyundai" on car hire forms. OTOH I was surprised by the Daewoo Tacuma which looks like crap but is OK to drive and fulfils its purpose. For the money it's better than a Scenic. However stacked up against eh C-Max, the Tacuma is s**te.

Cars weigh 50% more than they did 20+ yrs ago, which must be a factor. Average cars can cruise at faster speeds as well. I expect that the car manufacturers have had to change pad materials to cope with the extra weight/speed which has then caused this extra disk wear in modern cars.

No they don't.

A MK3 Mondeo Saloon kerb weight is around 1300kg which is only 200kg more than my 22 year old Ford Capri which is significantly smaller than the Mondy and extremely sparsely equipped.

Mark three Mondeo diesels have kerbweights over 1,500 kg. There was a little bit of a fuss about the mark three Mondeo when launched because most models seen on the road were heavier than the maximum permitted vehicle weight for a large number of permit parking sites and car parks in York.

possibly after braking hard from speed you keep your foot on the brakeonce you've come to a stop ?

Funny how some people always have the issue and othes never
