Not a big deal to switch them out...minor hole redrilling and fitting on firewall...definitely worth it!!
Do you have any recent photos of this swap---sounds highly interesting. Perhaps a write up detailing the process? Parts needed etc would be highly appreciated, at least by me.

It's interesting that that big a difference in rotor diameter is the same as going from stock tires at 30.5-inch to 35-inch diameter tires. It's not perfectly linear as it affects braking "leverage" but it shows just how much difference increasing tire diameter can have beyond increasing ground clearance.

Obviously extra vehicle mass doesn't help either. My stock brakes/tires don't stop great at 7,000 pounds, so 10,000 pounds would make it that much worse.

Re: LARGER BRAKES FOR 17 WHEELS

Not trying to Hijack this thread-JWA-Replacing vacuum booster with Hydroboost was really pretty easy.

1. Remove master cylinder and vacuum booster
2. make templater for hydroboost threaded bolts.
3. drill holes in firewall/i.e. open up existing holes essentially.
4. bolt hydroboost on and master cylinder on.
5. bleed brake system/I used vacuum bleeder worked great/also follow hrydroboost bleeding directions -easy
6. dont push to hard on brake pedal-it might put you thru the windshield-LOL

note: Bought new hydroboost for a 1978 Ford Thunderbird I believe-found an old one on a OBS van and got part number which gave me the idea to do it in the first place-$ 175 bucks or so I think

My original master cylinder worked perfectly with it-lucked out

DO IT-EASY
