Hi, I have 2 questions on the 1LE conversion with tall spindle on my 66.

1) When I did this on my 72 I just used the 12mm studs. on my 66 I don't want to do this, I have heard of people who have found a 7/16 stud that will press in without drilling, anyone know what this application is? Anyone have a recomendation on the length? I plan to use 17" torque thrust II's probably with gorilla lugs.

2) Converting from drum with the tall spindle requires different length hoses. On my 72 I had used stock rubber hoses for a 70 B-body with discs. I want to use Braided lines for my 66, I am not sure if they make that application in braided. Who here has done the 12" disc, b-body spindle conversion with braided lines? what application did you use? Thanks in advance!

A- I looked and looked thru several catalogs in several independent parts stores and didn't find a drop-in stud.

2- 69 Camaro disc brake flex hoses are a bit longer and should work. It depends on which caliper you are using, the hose connection is in different locations on various calipers. Check the length of the stock 69 hoses at a parts store. I "know" that they will make a braided hose for the camaro.

When I did mine, I went to 1/2" studs to match the new axles in the rearend. I remember looking for a while in the books before finding one that would work. I ended up having to drill the stock 1LE holes out a bit, then press them in.

The hoses do depend on what caliper you are using. My suggestion would be to simply use the stock Chevelle calipers and then the stock Chevelle hoses. You can get replacement braided hoses for the stock Chevelle, so they should bolt right up.

Good luck,
Bill C.

On my 72 the stock a-body disc hoses were way to short with the 84 b-body caliper I used. Thats why I went with the 70 b-body disc hose. Do you Think if I use the F-body calipers that the hose will mount in a different place thus allowing me to use the stock disc hoses for the 72?

BC, what application did you use the 1/2 studs from? what manufacturer/model?

Thanks!

The ’70 Chevelle calipers fit these spindles without any modification. You can use ’69 Camaro front disk brake hoses with the Chevelle drum brake hose frame brackets, they are a few inches longer. The stock Chevelle disc hoses will no longer fit. Be sure to use the correct “Banjo” bolt. Napa #82701 is 1.1” long. You can also use ’78 Camaro hoses but you will need to use Banjo bolt Auto Zone # 313935 which is .9” long. The ’78 Camaro hoses are cheaper and do not have to be special ordered. I found this out after already purchasing my ’69 hoses, so that’s what I used. http://hometown.aol.com/smartasreality/page12.html

Thanks for the info about the front? Question, would the rear braided hose from the 69 or 78 F-body work on the rear of my 66 since they usually sell the 3 as a set? Thanks!

Fo Fdyfo, when you say above that the stock chevelle disc hoses will no longer fit, do you mean they won't fit because they are too short, or they won't fit into the drum brake hose frame brackets? In my upcoming conversion on a 69 cutlass from drum to disc, I intend to modify my drum spindle to accept the disc brake caliper brakets,which I have from a 70 chevelle. I also have the hose frame brackets from a disc 70 chevelle car. So I am wondering if stock 70 chevelle disc hoses will be long enough, assuming I buy 70 chevelle calipers. Comments?

mrabody, i dont know. but if i had to guess i would say the rear hose will work.
bhawk,
the stock chevelle disc hoses will not fit into the drum frame bracket and they are too short when you use the b-body spindles. you should use the chevelle calipers, it puts the hose mount in the right spot. i would not use the disc hose to frame brackets. use your drum frame brackets wether you are doing the b-body conversion or not. the disc hoses are too tight. use either the 69 camaro hoses or the 78 camaro hoses with the right banjo bolt and you will be better off. the stock disc hose is to tight even on stock disc brakes, i have not even tried to fit a stock disc hose on the b-body conversion. maybe it will work, but when i put my car on the lift i dont want that rubber line to be pulled as far as it can possably go because the suspension is letting all the way down. http://www.chevelles.com/showroom/FO_FDYFO/frtdisc1-8-04-crop.jpg

Just to clarify, when I did the conversion to B-body spindles and such, I already had disk brakes, so I just re-used the disk brake hose brackets. I used the stock chevelle calipers with the 1LE rotors and the stock hoses fit just fine... in fact, better than stock since the caliper gets raised up about an inch. If you do use the b-body calipers, the hose mount is towards the bottom instead of the top, so you will need longer hoses. I'd definitely check into the others as listed since they seem to be cheaper and easier to find! You should be able to get the braided hoses for either application and should fit fine, just be sure to match the right banjo bolt to the right hose as they do differ.

As far as the 1/2" studs I used... I have no idea what application I used. I basically guessed at what shoulder/knurl length I needed, overall thread length I needed, then just set to work looking thru the catalog until I found something close. It was a dorman catalog. Also keep in mind that when I went to the 1/2" studs, it was when I made the switch from the 1LE rotors to the Corvette rotors fitting over the hub made from an old rotor. Because of this, I think the studs may have been about 1/4" longer to accomodate the thickness of the rotor pad. My very sparse notes that I still have show that I may have used dorman part number 610-289 for the studs. I do remember having to grind down a little of the shoulder that was poking thru when the studs were pressed into place.

Anyway, good luck,
Bill C.
