disc replacement

[blutopless2]

has anyone had to replace discs yet on their golf or jetta?
how many k's did you get before replacement? how much did it cost?
just had mine serviced ... done 50,000k's and mechanic said discs look really good, he expected that i would need to replace them soon but dont need to.
mixture of suburban and freeway driving.

What disks mate? If you mentioned braking pads it would be OK at 50K km to change, but disks - not, BS. They would machine them first... I got 75K km, and they were not machined yet. I had Camry with 140K km with original disks and that car was heavier than Golf...

Sometimes disks can last for 60 to 100,000ks, for others, 25 to 40,000ks.
Depends on driving styles, terrain, traffic types. stop start etc etc.

It is normal nowdays to just replace the disks. Machining is getting to be not so popular.

Disk prices can vary from $100 to $300 each depending on point of sale and vehicle.

Have to agree with Bazzle here.
Looked into doing the rotors on my Holden Adventra.
Got the new disks for $119ea from Motor Traders but to get the old ones machined was goind to be about $150. I figured the rotor with more metal would stand up longer before it needs work than the thicker/newer rotor.

My Jackaroo has 155,000ks, still on original rotors and pads replaced 15,000k ago. Part of the reason brakes on older cars last so long is asbestos pads, which can no longer be used. They were largely dust free as far as dirty wheels were concerned.

However, that's not the way the Euros approac braking. They use rotor metal and pad material as sacrificial friction material.

Machining rotors on a Euro is a very bad idea in 90% of cases - they will end up too thin and expose you to a premature brake failure.

Luckily rotors are pretty cheap.

Oh, OK then, I thought japs and euros were the same in that department!

Spot-on, Gerhard.

The metal used in discs on European cars is a lot softer than that of Japanese cars. The discs are designed to wear. Machining them accelerates that wear. The brakes on VW passenger cars wear surprisingly well. I can pretty much remember every car I've replaced pads and/or rotors on in the last two years I've spent in a VW dealer.

From my observations, Touaregs and Transporters are the worst for brakes. Interestingly, two 3C Passats I've worked on, needed rear pads at 60,000klms. Another thing I've noticed is that I've never experienced brake shudder in any VW I've ever driven.

I have a vague idea that VW brakes are designed to work well (to a certain %ge of normal efficiency) if you suddenly lose the power assist (eg brake servo fails). To achieve this the pads and disks are quite soft and so don't last as well as some other vehicles.
