'73 911E front rotor question

[tmctguer]

i'm about to begin a front brake job on my '73 911E. i will be replacing pads, turning the rotors, and bleeding the brakes to replace the fluid.

i read the shop manual (imagine that !!) and found that the min/max front rotor thickness is 18mm/20mm. my front rotors are now at 19mm and have a few minor ridges in them.

two questions:

1). what is the likelyhood that more than 1mm will have to be removed from the rotors when they are turned?

2). should i turn them and put new pads in, or should i splurge now and replace the rotors?

3). what brake pads are recommended for 90% street, 10% track use?

I doubt that turning the rotors would take off as much as a milimeter, so I would imagine it would be OK to have them turned. But, you will have to replace them next time around. However, new rotors aren't that expensive & if you're inclined to replace those you have now, that would be a good idea too. It's about 6 on way & half a dozen the other. Somebody else can comment on the pads.

Buy new ones. I turned my present rotors at a similar level of wear and they lasted about 3 months before warping again. for the cost and hassle I'd go for new next time. Still stop ok though.

I second that,

Just buy replacement rotors, overall with new pads, you will have the best results. I did the entire job myself 3 years ago, it's quite simple.

Don't throw out the old ones.If you do ,throw them my way, that might work out as an upgrade for my little ol'e 912 someday.Your only 35 miles away,and I'll trade you a 12 pack for to boot!
