Wilwood Parking Brakes on an Alfa transaxle.


The rear brake calipers are a weak point of the Alfa transaxle, They are difficult to work on or adjust, and are unreliable to boot. It is the mechanical parking brake function of the caliper that makes them unreliable and prone to sticking and seizing..

While you can replace the rear calipers with a number of aftermarket calipers, these lose the parking brake function. Since you need a parking brake to register the car in most states(USA), these aren’t an option.

The only parking brake worth a damm, IMHO is the kind you find in the Alfa Spider and some other vehicles; a drum brake hidden inside the top hat of a disc brake rotor.

Wilwood makes a number of kits to convert big American muscle car with rear drums to rear disc brakes. These kits retain a parking brake function by placing a drum brake style parking brake inside the disc brake rotor. Wilwood makes these kits with both solid and vented rotors.

I think this assembly would fit on the Alfa transaxle. I have done some measurements and the bolt pattern for the stub axles, is a square 60 mm(2 1/3 inches), the space we have to work in, from the transaxle case to the base of the CV Joint is 77mm( 3 inches ).

If all this works out we would end up with rear Wilwood brake calipers, a choice of rotors( solid, vented, floating) and a real parking brake.

Is anybody else interested in doing this ? If so could we approach Wilwood as a group ? . Dose anybody on this list have any contacts at Wilwood Brakes in California? If necessary I can supply an empty transmission case, stub axles, drive axles and other parts for a prototype.

Bye for now

That would be nice.

We just did the new 4 pot GyroDisc/Group 2 floating aluminium hat brake conversion on the front that uses Wilwoods! WOW! I am doing the rears next!

The setup gives you a much larger vented front disc, 15” wheel fit, vented rear disc (with floating aluminium hats back there too) with nice new reconditioned rear calipers and OEM handbrake fit.

This is an Amazing bolt-on mod that was so worth it. Chris from Group 2 was already running the full rear conversion as well – It is amazing how nice completely rebuilt rears with the spacers and all new seals are with the thicker vented floating alumium hat rotors back there...

He had good reliability and zero fade on Friday (in HUGE heat...) This is the same setup that Jes (AR4me) is running on his street Verde…

It would be nice if there was a Wilwood back there too...

On the 3.7s we did the outboard conversions and this cured much of what ails including heat and quick pad change-over...
