Replacement Discs

[Guest]

Hi

Does anyone know what the expected mileage you can get out of a set if discs?

I've a 02 Boxster S with 48,000 motorway miles.

I've just replaced discs and pads all round. My local OPC said that I was lucky to get 48,000 miles out of them.

I could understand if I was on my 2nd or even 3rd set of pads. However I was still on my 1st set of pads!!!

Anyone else with same problem?

It depends on how you drive your car but I would expect the disc wear to be proportionate to the pad wear.

48000 miles on a set of pads is very sedate breaking for a Porsche![&:]

48K on a set of discspads! Someone doesnt drive the car very hard!

I don't get chance to go fast anymore. 9 points......

I'd say 48K is VERY good for both - my discs lasted 12K and pads 14K........might've been a track involved though []

I was surprised that I needed by discs changing at the same time as the pads at 36,000 miles.
Perhaps it is one of the reasons that the brakes are so fantastic.- High friction-High wear

correct me if I'm wrong (and somebody probably will!) but the original Porsche/Brembo pads are loaded with brass to dissipate the heat generated more evenly and quicker, the downside is accelerated disc wear.

I swapped mine to carbon fibre pads at 30K and at 48K my discs are still OK, the braking difference is only noticeable on a track and I use this car on the road, albeit quite upto its abilty if you get my drift.

Actually thats not quite true my driving abilty which no where near matches the boxster's capability so its actually my ability!! And will I still feel comfortable watching F1 with no BGP!!!


By the way has anybody else noticed the subtle change of discs to rotors in the motorworld??! Why are they now rotors instead of discs? Why is Jif now called Cif??!

 

[GreigM]

rotors is the american phrase for discs

 

[matt643]

Yep, YEE HA! And all that, but as I do not throw out the trash, sit on the couch or polish my hood [X(] why should I call my disc's rotors!

Having worked in the States for quite a while its amazing that we can understand everything they say but explain that you have left something in your boot and you will be met by blank stares!!

I blame Mr Gates and his US English option in Windows.

Which carbon fibre discs did you fit?

 

[matt643]

I'm on the standard steel discs at the moment, the pads used were from powerstop brakes who use a kevlar type material for their pads which seems to work very well.

I did notice a reduction in black dust as quoted by powerstop but its still a pain on my 'S' alloys. I have never suffered from brake fade since swapping over to the Aramid based pads and they have lasted well with minimal disc wear as quoted on the powerstop website so I would say they are a good bet. Cheaper than OEM parts too!

By the way has anybody here got an M3? What do you think of it?? Family commitments require four seats and I cannot stretch to C4S at the moment.

HELP! THE DARK SIDE BECKONS!!!

Sorry I did mean pads
I take it you used the "Green stuff" EBC pads
I have thought of using these for sometime but wanted to wait until I got a good recommendation.

 

[matt643]

They are good pads, another bonus is that they dont squeel like the originals!

Changing pads is also simplicity itself, took me about half an hour for both sides the first time I replaced them.

Yes, green stuff!

Matt,

I'm just about to change my pads for the first time too, my only concern was keeping the pistons back when I put the new pad in. Is this easy enough...got any pointers, tips?? I'm going to follow this sites advice.....u seen any better ones?

Thanks

Hi,

Once the pistons have been pushed back into the caliper they will not come out again unless somebody pushes the brake pedal so lock your doors!!

Keep an eye on the brake fluid resevoir to make sure its not getting too full and make sure that the pistons are fully pressed back into the caliper before fitting the new pads or it will be difficult to get the pads into the caliper.

The site you have looked at is the same one that I used as a reference and its pretty damn good!

The Brembo/Porsche brakes are really simple to maintain because they are used on competition cars so pads sometimes need to be changed really quickly during a race, I've got to say they are probably the easiest calipers I have ever worked on.

Unlike the headlamp disaster I had the other day.... Post to follow! All I can say is check the electrical connector is aligned to its retaining bracket BEFORE pushing the lamp assembly back into the wing.

Matt,

Great thanks a lot, so I'll just go with the levering technique he uses to push them back, then they should stay there.....I'll keep my eye out on the brake fluid resevoir too.....
Not looking forward to undoing all those nuts tho....[]
