I had a question regarding whether the big front brakes off a granada would work on my truck. I just picked up an unfinished chevy pu that I was told had a mustang 2 front clip. Just tryin to find out if the bigger granada brakes would work so that maybe I can upgrade more by visiting picknpull. any helps appreciated. thanks
The rotors will go on with the stock brgs. but u will have to get a caliper from a mid size gm or some guys are using late model mustang. The only hard part is to make a bracket. When I did it it took a day, cause it was first time.
So I could get the 11" rotor from a granada or maybe some other ford but couldnt use ford calipers. Or do you think the whole spindle may bolt on?? thanks man just tryin to build my ride on a low budget.
Wrong kinda questions... this is for questions and suggestions about the HAMB, not ya car fellas. might get more people to see it if its in the right forum?
Granada spindle, hub and brake assemblies interchange with early ('65-'73) Mustangs (and other Ford compact/intermediates), NOT with 1974 and newer Mustangs. The entire front-end was redesigned on the Mustangs in 1974 and again in 1979. The 11" Granada rotors, however, will slide on with minimal problems. You'll need to buy or make a bracket for whatever caliper you choose to use. You could make a bracket for the Granada caliper, however, many places make a bracket for a late model GM caliper. Check out the Mustang II front-end section at www.polepositionrp.com for ideas on the brackets and Granada rotors. I'm sure there are plenty of places that offer Mustang II brake upgrade brackets and parts. Cheap is good, but brakes are not a place to try and save money by using junkyard parts....just my opinion. Reman stuff is plenty cheap these days. -Mike.
Mike is right dont skimp on the brakes $$$. Nobody wants to be in front of a car with custom wheels and NO BRAKES. Buy new rotors and bearings at your local parts store Wagner part number # BD60431 get it in a generic brand and it should cost under $40 (we buy them for $22). Bearings and seal and rotors under $100 NEW. If you plan to use a manual brakes use 4 piston calipers, they require less volume and less pressure. (make your own bracket) They are sold by many companies and there are a lot floating around on Ebay. Cost new is under $200 to $250 with pads. A brake kit for under $400 new! Why 4 piston calipers? Single piston calipers were designed so car manufacturers would not have warranty problems with warpped rotors because the single piston caliper is more forgiving. Single piston calipers "slide across pins and squeeze from one side" this action alone requires the piston in the caliper to more a LOT! Therefore it requires more brake fluid. MORE BRAKE FLUID requires a bigger maste cylinder .....bigger master cylinder produce LESS pressure. It is like putting your thumb over the end of a hose, the small the hole the greater the pressure. BUT you can not go small on the master cylinder if the volume requirements of the caliper exceed the m/c out volume. To figure how much pressure your master cylinder is putting out: C = pedal ratio D = pounds of pressure apply by your foot E = area of you master cylinder F = pounds of pressure out of the master cylinder C X D /(divided by) E = F Example: If you have a 1" master cylinder the area equals 1/2" x 1/2" x 3.14 = 0.785 Square Inches. So, 100 pounds (of applied foot pressure) X 6 (pedal ratio) divided by 0.785 = 764 pounds of pressure. If you have a 1-1/8" master cylinder, 100 psi X 6 (pedal ratio) divided by 0.9935 = 604 pounds of pressure. Here is some info on master cylinder with "constant" of 6 to 1 pedal ratio and 100 psi being applied. 3/4" master cylinder = 1359 psi 13/16" master cylinder = 1158 psi 7/8" master cylinder = 998 psi 15/16" master cylinder = 870 psi 1" master cylinder = 764 psi 1-1/8" master cylinder = 603 psi OF COURSE it would be optium to use a "flat rotor" because it does not warp as easy as a OEM type, but since cost is the issue, you can replace the rotor a few times since you proberly are not driving it everyday. So, for under $400 you have the same disc brakes Heidts offers only without polished calipers. Think of all the money you will be saving by not having to buy a booster. NEW master cylinders are under $60, I would not recommend by rebuilt master cylinders. And you wont even have to buy a vacuum pump when you dont have vacuum! Vacuum pumps are for people that buy Brooklyn Bridges. For additional information go to: http://www.hotrodheaven.com/tech/brakes/ DSO
