want to turn stock 914 front brakes into supper brakes?
Purchase Porterfield brand pads. High Performance House sells them. They are pricey pads, but I have experienced no better braking than with them on my stock system 9except for teflon /stainless braided hoses. Even my master is stock.

Go with the Porterfields, you will not be disapointed. It was like night and day between them, and the regular pads.

Porterfield man, Porterfield

No conection to Porterfield Company, just a heck of a satisfied user.

My experience with carbon pads (performance friction) which I assume is what the porterfields are is that they are awesome, but only when HOT. At normal temps they are no different than std pads. Correct me if I am wrong about the porterfields.

I have mazda RX-7 4 piston calipers on my -6 and they help. Still have the std rears and prop valve and the std m/c. If I recall, they have about 12% more piston area than the M calipers. Obviously, the mazdas are not a bolt-on. Strut mods are required.

Hey Bernie, where did you get this block at? I had to use the same junction I used to replace the rear proportioning valve. This looks much cleaner. Where did you get it?

I just put the Volvo calipers on the front of the race car as Bernie did and they seem good. Tere is a little more pedal travel but not bad. I had BMW front and back and had some trouble with brake fade at a couple of races in Mexico since there was not as much heat disapation as I needed. I also used a 36 section of brake like on each side of the front with some loops so I have a much larger fluid volume up there which was recommended by several BMW 2002 vintage racers as that is what they did. I have had the 23mm m/c for about 2 years and it works well. I plan to go to the 4lug adapter kit shortly I hope and will do some picts when finished.

For the adapter block check out the Datsun 311 roadster board as they have a good article on installing the Volvo calipers and I got my blocks from their source. Here's the address: http://www.311s.org/

Cool, thanks Bernie, I will have to get me a set and upgrade the Chalon. I used seperate lines and a T like in the back. Looks like a spider or something down there. I like the block much better. Its cleaner. Besides, I may put them on the 74 also. A fast car is only as good as its brakes.

I got a few PMs about the mazda calipers, so I will add a few photos here of the strut and jig for modding the strut. It's a little hard to see, but you can see the upper mount weld bead in one of the pictures. I did this about 5 years ago, so there may be better options out there now.

I've been following this topic and lookin at some of the other s about 914 brakes. I'm curious because I'm runnin the 914 rear caliper on my Type III. The front caliper on mine is the same, but no E-brake setup, of course. My master cylinder is also 19 mm. Does anyone know the stroke of the 914 19 mm cylinder? My VW one is 15 mm. My rear brakes don't seem to work as well as they should. I'm tyryin to figure them out. I have a clue now that I know the MC is the same size that they are probaby frozen. Any help would be appreciated..........Dad (IMG:http://www.914world.com/bbs2/html/emoticons/driving.gif)

I'm running the Volvo calipers on the rear of mine. I got around the need for the external pipe work by drilling through from the bottom piston bore to the top one, and then put bleeder nipples in the redundant holes.

For solid rotor conversions, you can get brand new calipers for $69 each.
