1979 928 brake upgrade

[barman]

Hi all, I want to improve the original brakes on my`79 car. Its like stopping a freight train at the moment. Could I fit S4 calipers and discs on a basic `79 model 4.5? Or any other suggestions . Thanks.

Post a price and maybe he'll respond.

Are you locking up your brakes now, if not you may not be pushing hard enough or perhaps have some booster issue. The brakes on a 928 are not like most cars they are progressive, which means press lightly, slow lightly, press hard, slow fast.

Find a safe place and get the brakes warmed up and see what they can do. Good pads etc. are also important.

Or pass out. The S4 parts often sell for more than a whole 79 928 does.

It's a Porsche! I thought it read our Brain Waves for Progressive Brake Pressures?

No, not on the 928. Its a $15,000 option on the Panamera though

Price? I really don't want the rotors or bad shocks.

Pm me for price and open for discussion. I wouldn't want old shocks either. But the front shocks do have the adjusters.

Consider what Dangler said. When my booster was out, it WAS like trying to stop a train. New booster is on, and what a difference; like night and day. I have driven older cars with no brake assist, and they were 10x better than the 928 with non-op booster. Now the 928 brakes like my '05 BMW = awesome. If you are having problems, it would be my guess that it's probably not due to having calipers that are not big enough.

I have a set of front brake calipers from a 85 Porsche 928S im sure they would be a nice upgrade to your 79s brakes. $120 plus shipping and they are yours.

[MPDano]

What do the "S" Calipers look like? S4's, Brembos? Post pics for all.

[Dan951]

They look like normal calipers. Nothing fancy. There about the same size as a S4 caliper just a tad shorter.

[Fabio421]

The calipers on all of the cars 78 - 86 are sliding calipers not the monoblock style of the S4's. The calipers on the 84, 85 and 86 cars are slightly larger than the previous years.

Since no pics available, they are just larger versions of our OB Calipers?

Yes. Sorry for not having pics. I just gave a set away to Firemed when I upgraded to S4.
