We just inherited a 1966 Duetto 1600 I want to change over to Ate brakes from Dunlap. What do I need to purchase and change to do this. Thanks ahead for any help.

Upgrade brakes from Dunlop to ATE on 67 Duetto

Getting ready to reassemble my 67 duetto. I have front spindles and hubs from a mid 70's spider and interested in converting to ATE. Looking for advice if anyone has done this before and also looking for a rear axle to complete the conversion. Can I use the same master cylinder? Will the ATE...

Why change from Dunlops? Unless you are going to put lots of miles on the car simply rebuild the front Dunlop calipers, put on new rotors and pads. Parts will probably outlast you and me. This way the car is as intended and unique with the Dunlop parts. Its great to see a mechanic look at the rear setup and go Huh!

I would be ok with a good rebuild. The only place I know that rebuilds the Dunlap calipers (Alfastop) doesn't export to the US. My calipers are frozen and in bad shape. do you know a good rebuilder in the US?

Depends a bit on where you are in the US. Here in Orange County, California, we use ABS Power Brake on Lemon Street in Orange (ya can't make this stuff up!). Karps in Upland is another local place. Dunno where you are, but there may be similar services in your area.

I was one of the contributors to the thread that alfaparticle cited in post #2 and have converted both my Sprint GT and Duetto from Dunlop to ATE. While I understand patonycam's goal of keeping things original, the greater availability of ATE parts was the deciding factor for me.

I have Milano Aluminum Brembo calipers on my S2 Spider and they are on uprights from an earlier car which may have had Dunlops. If that is the case and Brembos have the same mounting bolt centers as Dunlops then they would be a good upgrade.

That

The Brembo brakes sound good if the same spindle , hub assembly can be used from Dunlaps. But what are the costs?

 

[alfaparticle]

I bought my calipers from an online junk yard for about $100. Milano rotors are vented and thicker than Spider rotors and the Brembo's have a spacer detween the two halves of the caliper that is easily removed. But double check the fitting on your uprights. There have been posts in the past from Alfar7 and others.

Thank you for the information.

Change over is a direct bolt on from later Spiders using the laters front spindles. Use later larger front calipers. Rear axle from Spiders with LSD. Choice of 4:56 or 4:10. No mounting for anti roll bar but works fine without. If you are sticking with 1600 the 4:56 might be a better option. Dunlops are ok if you want pure stock, but they can be pushed to limits if driven spiritedly. Today's driving, the vehicle in front of you has a shorter stopping distance than 53 year old brakes..APE in NorCal should have used parts you need to rebuild.
Cheers, Jon

If you change to S2/3 spindles then you should be able to easily sell your current ones to someone who wants to fit Brembo's which are preferred for performance cars.

AlfaStop certainly ships to the USA. I just got Dunlop parts from Tony 3 weeks ago. Prices are not cheap but quality is good. I got everything I needed to rebuild the complete system: pads, rotors, rear cylinders,stainless flex lines, front pad pins and front caliper lock tabs. Fortunately, the front calipers were rebuilt by last owner and are fine. There are numerous places that can rebuild the fronts like Apple Hydraulics or White Post Restorations (I have never used either of them, so no endorsement) that have internet sites. AlfaStop has rebuild kits for front calipers. I am sure a quality local shop can install the rebuild parts. The key to working with AlfaStop is to call him and discuss after asking for a quote. Goodluck.

Hi Jon thanks for answering my thread, I tried to email you but it would not go thru. Not sure why. Would like to talk with you about parts possibly. Thanks Don
