I just purchased this car from a fellow R Gruppe member. It has 20k original miles on it and the brakes have not been touched. Although it stops fantastic, I am guessing that it is probably near time for a brake job. Here are some questions I need help with:

Should I replace the rotors or have them turned?
If turned, how much should they be turned?
What pads and brake fluid should I use (street driving only)?
Where is the best place to buy the parts needed?

Thanks.

Paul

PS Here is a pic of the car...very fun!

 

I wouldn't turn these rotors. Better to just let the new pads "bed" into them as is. Pad's are cheap, the rotors cost an arm and a leg.

 

Also, these rotors definitely look unusual

 

Yup, big and floating. Good luck finding a replacement for any amount

ATE Blue or Gold, Ferrodo DS2000 pads. IMO

 

You never really want to turn cross drilled rotors. I assume that is what you have. I would replace them as expensive as it is. When you turn the rotors, you turn life away and they will simply warp that much faster.

try Porterfeild pads and ATE gold.

 

Thanks for the input. I'm going to see if the rotors can just be used again!

 

I have a spare set of 1979 fully floating rotors with mounting bells, unused. I have been storing them under my bed so they wouldnt rust!

They are about £385 from any source each now, I am open to sensible offers.

Cheers

Barry

 

Thanks for the offer...I will keep it in mind!

 

Paul:

Good, sound advice from Stephen,...turning drilled rotors is generally bad practice.

FWIW, look at the Brakes page (http://www.rennsportsystems.com/brakes.html) of my website to see our custom Brembo rotors for these cars. Those are a 304mm/32mm front rotor with a billet, hard anodized flat hat that bolts onto your hubs as a direct replacement for the too-soft OEM Zimmermans used on the 78-79 930's.

These are not full-floaters, but they outlast the stock Turbo rotors 3:1.

Nice looking 930. Is that the same one featured in the August 04 issue of Excellence?
