300zx Brake Conversion HELP!!!!

[tougegtr-33]

I am having problems with my 300 zx brake conversion in the front. i am doing the 300zx brakes on an s13. i just converted to five lug. But when I put the caliper on the rotor and bolt it down to the hub on the back it makes the rotor alittle crooked so when I put the rim on there and bolt it down it pushes the rotor to the one side of the caliper and locks the brakes in the front. its like that on both sides.

The only thing i didnt do was. I bought these sleeves so I didnt have to drill out the struts, but when i put the strut bolts in, it fit perfect. i didnt see why I have to put them in. is that what is making it do that??

Are you mounting the caliper on the right side of the tabs? Dunno if its possible to mount it any other way but its an idea. Also you do have the calipers on the right side of the car? Bleeders are supposed to be on top.

^ ill check all that tomorrow. thanks man. i hope it something simple. theres isnt a spacer or anything i have to use to mount the 300zx caliper to a s14 hub right?

[super240sx71]

No mine are bolted straight to the spindle

k. is there a difference in the rotor width on na and turbo model 300zx?

[super240sx71]

Yea im pretty sure they have diff thicknesses.

i went to autozone and asked to see if they are the same rotor and they said they are the same. you think if i have na calipers with turbo rotors, it could do that??

The "26mm Aluminum" calipers were used ONLY on 1990 non-turbos. They used a 280mm x 26mm rotor.

The "30mm Aluminum" calipers were used on 1990 Twin-turbos and ALL 1991-1992.5 300ZX's (both turbo and non-turbo alike). They used a 280mm x 30mm rotor.

The "30mm Iron" calipers were used on ALL 1992.5-1996 300ZX's (both turbo and non-turbo alike). They also used the 280mm x 30mm rotor.

Figure out what caliper you have then make sure you have the rotor.

hmm thanks dude. i might have the 90 na calipers with a turbo rotor. you think cutting the rotor down would do the trick?

[super240sx71]

Im not sure if thats even the problem, or if its safe to cut that much off. Just take some measurements first too see the prob.

[tougegtr-33]

Alright will do. ill go see what calipers and rotors i have in the morning. thanks man!

[super240sx71]

No prob.
