Question : 5 x 115 rear discs on L-body

[berettaguy]

Hi folks,

I have a 91 Beretta that was upgraded to the front STS brakes & 5 x 115 bearings many moons ago. I haven't modified the car in ages and was wondering what the consensus is for upgrading to the 5 x 115 pattern and disc brakes in the rear is these days? I remember it used to be that you had to find a FWD Pontiac STE, rob the rear brake parts off of that, and then do so welding on your stock beam axle. Hopefully something better has come along in the last decade! Thanks in advance for your help & happy motoring!

I haven't heard of anything thats boltable for 5x115 in the rear. I have N-Body or F-body brakes up front, I can swap anytime I want... those are 5x115 and the rears I currently have are 5x100 Neon Sport discs with internal parking drum. It doesn't bother me since I have dual pattern rims so moving tires is fine.

I've done the Dayton rear disc swap, rotors fit, and you just need to make a bracket out of 1/4" material to mount the caliper, and move the ebrake cable around, I'll see if the pics are kicking around still, but this retains the 5x100 bolt pattern. If you really want the larger bolt pattern you can have it machined on the hub and disk$$$

If you do the daytona disc swap you don't need to make any bracket to my knowledge... Use the whole stock bracket and machine it to fit the bearing, same as what the J-body guys do.

So if I'm understanding you correctly, you are suggesting doing the Daytona rear brake swap, but have the Daytona bracket machined to use a 5 x 115 bearing instead of the usual 5 x 100 Beretta one. Would you suggest the rear hub from the '99 N body to have this done? Then use the N body rotor and Daytona caliper with e-brake?

I have dual pattern wheels now, but they need to be replaced due to wear & tear, and I would like to move to a single pattern wheel when I do so. I could even go back to a single pattern spare, as right now I have a larger spare dual pattern wheel from a Caddy IIRC.

Has anybody tried to use the rear N-body hub bearing & rotor with the Daytona bracket & caliper?

All chrysler wheel bearings bolt the same way for the most part. So you can use a intrepid bearing with a neon back plate. Then use the 5x115 rotor from intrepid.

The backing plates look the same so I would just grab the entire entrepid setup.

Now that sounds like a great plan, thank you so much!

[bob442]

Yeah, I never knew about using the backing plate too from the Daytona. Thanks, too bad I dont own a j body anymore :,(

Would I still need to redrill the backing plate if I use the Intrepid bearing? Also, does anyone happen to have the years or part numbers of the Camaro master cylinder and j-body distribution block I have heard about?

Your options are to redrill the beretta axle for the intrepid bearing and leave the backing plate alone, but the axle is tough to re drill. OR find a gm wheel bearing that is closer to the beretta axle and machine the backing plate to fit that. I guess redrilling the beretta bearing is also an option is theres enough meat
