Brakes

[pocketscience]

On a couple of recent spirited drives I’ve found the brakes a little wanting at times. They are stock T setup and consumables (incl rubber lines) were refreshed as part of recent restore. Any suggestions to improve the stock setup? I’m never going to track the car so don’t need/want to go overboard.

Sierra Madre are selling PMB brake line sets now I see... I am considering some for the Carrera 3.0.

I would look at putting racing brake fluid in - that improved the performance and pedal feel in my swb on the few occasions I ran it in supersprints / regularity.

In addition (depending upon what front struts you have) its possible to put 911SC style discs and calipers on. An SC would be 100-150 kgs heavier, so brakes are bigger / better .

All of the above combined may help?

Or you go crazy and fit Boxter monobloc type brakes. Quite a few vendors developed kits for early cars some years ago.

Hmm, I didn't see those PMB lines when I placed my last SMC order a week or so back. Bugger. Good tip on the higher spec fluid though - that's an easy one. I'm still running the stock front struts and I'd consider moving to the SC setup a bridge too far.. ditto with the Boxster setup.

Were the brakes on the S from '70 any different? I think I read somewhere they were alloy, so lighter yes, but were they an improvement in other ways?

What bolt hole spacing do you have where your calipers mount to strut, 3 or 31/2 inch ?

[pocketscience]

3" bolt spacing.

I am running one of Stan's Boxster kits , nice but too efficient.

They heat the 3.2 Carrera discs too much resulting in warpage.

I have even tried the standard pads but same problem as with the Pagid RS 4's

Some one suggested I need a floating disc kit ?

3" bolt spacing.

These might be a good option.

Thanks, will take a look. Maybe I should just initially go with SS lines, performance pads and fluid and see if that improves things - and if not, look at other options..

I'm going to keep my current calipers, and just refresh everything. I see two options for refresh kits for the M calipers - with or without "Disc Wobble Compensation". I understand the pistons are different depending if you have that or not- but any way to tell which I have without first pulling the calipers apart?
