Impala SS Rear Disc Brake Brackets
 

Here is my latest design of the Impala SS rear disc brake brackets. These are laser cut out of 1/4" with 1/4" spacers stitch welded on and then tapped M12 x 1.25 for the caliper cage attachment bolts. These brackets will bolt onto the truck 12 bolt rear differentials from '64-'82 and the 10 bolt truck differentials from '79-'87. The price on these is $115.00 plus a flat rate shipping of $9.20. This pricing is always current and up to date. PayPal is preferred, but I will also accept money orders. The package includes one pair of brackets plus grade 8 fasteners to attach the brackets to the axle tube flange and the metric bolts to attach the caliper cages to the brackets. This setup is for the 5 x 5 bolt pattern.

If you would like a set, post in this thread, send me a PM or send an email to captainfab454@hotmail.com, and I will give you the ordering and payment instructions and current lead time.

Another nice product :metal:
What did the impalas use for e-brakes?
will the impala rotor fit the axle with out any modification?

Re: Impala SS Rear Disc Brake Brackets
 

The Impala e-brake was a shoe setup inside the rotor which would be a little difficult to adapt to a 12 bolt truck diff. The Impala rotor fits over the axle flange with nothing more than slightly opening up the center hole to slide over the step on the axle flange. A die grinder and a flap drum will do it is 5 minutes or less.

Re: Impala SS Rear Disc Brake Brackets
 

I'll take a set. Paypal on the way.

Re: Impala SS Rear Disc Brake Brackets
 

Do you use the truck rotor or impala rotor?

Re: Impala SS Rear Disc Brake Brackets
 

Uses Impala SS or Caprice/Roadmaster rear rotors.

Re: Impala SS Rear Disc Brake Brackets
 

I haven't received it yet.....as soon as I do I will send a set out to you. Thanks

Thanks for replying Josh. I see you got yours today, have you put them on yet?

I'm not aware of any 5 X 5 truck rotors that would work on the rear.

Re: Impala SS Rear Disc Brake Brackets
 

They're on there buddy. Fit and quality is perfect. Couldn't ask for a better product or better service. Thank you.

Re: Impala SS Rear Disc Brake Brackets
 

Thanks for the compliment Josh.....and for the purchase too :D

Re: Impala SS Rear Disc Brake Brackets
 

If you have spares put me down for a set. Do you have the part numbers for the brake set-up?

Re: Impala SS Rear Disc Brake Brackets
 

hey cap... do you also make them for the ten bolt rearends?

Re: Impala SS Rear Disc Brake Brackets
 

payment sent. Cant wait to see how this app. fits and look on my truck. My brother might want a set too so Ill let you know.

Re: Impala SS Rear Disc Brake Brackets
 

What year of 10 bolt? Are you referring to a 8.5 truck 10 bolt? If so I'm pretty sure the ddistance from the axle tube flange to the axle flange is the same as a 12 bolt. So they should work but I would need to verify that, unless someone here can.



I'm working on putting together a list of parts and part numbers. You basically need rotors, calipers, factory caliper brackets, pads, and hoses for a '95 Impala SS. You will also need a brake line adapter to go from metric to SAE.

Re: Impala SS Rear Disc Brake Brackets
 

What do you recommend for the prop valve when adding the Impala rear discs?

Re: Impala SS Rear Disc Brake Brackets
 

Well not having completed an install myself, I can't make a recommendation from experience. However I do like the tuneability of having an adjustable valve on the rear line. There seems to be a few different combinations that work for those that are running 4 wheel discs. Some have good luck with the disc/drum prop valve and an adjustable for the rear. Some switch to a specific disc/disc prop valve with good results. And others use only an adjustable valve for the rear. I believe that the different bore sizes of master cylinders as well as the piston size of the calipers used plays a role in what works as valving in a given brake system.

With that said,as for the Impala rear brake conversion, I think I might recommend seriously looking at the components that GM used on the Impala for a start. Although the weight bias of a pickup is likely to be a bit different than an Impala. Also the weight bias from one pickup to another will be different in how the truck was built. This is mainly why I believe an adjustable proportion valve is beneficial to the brake system.

BTW Scot, how did that booster bracket work out for you?

Re: Impala SS Rear Disc Brake Brackets
 

It looks great . . ... sitting on a shelf full of parts (Vette MC, Malibu booster, Porterbuilt Dropmember, 350/700R4, van tilt, blah, blah. blah.... Also should have a couple of steelies on the way :cool: .

The parts are waiting to come together but I've gotten behind on building the frame for my retroRod project so everything else is delayed as well. Should make for a busy summer. There will be a thread w/details soon.

Re: Impala SS Rear Disc Brake Brackets
 

Hello Captinfab,
what did the impala use for an e-brake?
is everyone using a rear disc with out an e-brake?
chas

Re: Impala SS Rear Disc Brake Brackets
 

The Impala SS used a shoe setup inside the rotor for an e-brake. So using These brackets on your truck won't give you an e-brake. If you need to have an e-brake, you'll have to buy the Camaro caliper brackets that glock35ipsc is making. Thanks for inquiring.

Re: Impala SS Rear Disc Brake Brackets
 

What front set up matches the ss caliper?

Re: Impala SS Rear Disc Brake Brackets
 

[quote=Dahawk;3299044]The Camaro or Impala's front calipers would match, but I don't know how you would mount them to the spindles on your truck. The biggest issue would be the thicker rotor on the trucks. The aftermarket might be the option for that. I'll have to do some looking and see if there is an OEM caliper that would work.

Re: Impala SS Rear Disc Brake Brackets
 

I have one set of these brackets left......I'll throw in a pair of Metric to SAE line adapters for free with this last set.

Re: Impala SS Rear Disc Brake Brackets
 

Capt....please check your PM's as I am interested.

I'm also curious to know what the diameter of the impala rotor is? Can you get me a measurement from the center of the axle to the highest point on the caliper? My wheel has a 7 inch backspacing so fitment is going to be close depending on the dimensions. Thanks in advance

Re: Impala SS Rear Disc Brake Brackets
 

r there any left i would like a set please send me an invoice
adsendejo@comcast.net
thanks

Re: Impala SS Rear Disc Brake Brackets
 

PM sent, I'll let you know in the morning. Thanks

Right now I only have one set left and Outlaw72 gets first dibs, so if this setup won't work for him, you're next in line. If I could get 2 or 3 more sets sold, I'd make some more.

Re: Impala SS Rear Disc Brake Brackets
 

hey captinfab
just so you know i would like to buy two sets thats not a problem. let me know either way

Re: Impala SS Rear Disc Brake Brackets
 

OK that's good. It looks like Outlaw72 will be taking the set I currently have, so I'll need to get some more laser cut. I'll get those ordered tomorrow and let you know a time frame.

Re: Impala SS Rear Disc Brake Brackets
 

paypal sent for the brackets and line adapters...

Re: Impala SS Rear Disc Brake Brackets
 

Nice job on these! :metal: I haven't made Impala brackets for a couple years now, so I'm glad someone else is. I still get PM's asking when I will make another batch, so I will steer them your way from now on!

Re: Impala SS Rear Disc Brake Brackets
 

I got some more on order and I should have them by the middle of next week. I'll let you know when they're ready to ship. Thanks

Re: Impala SS Rear Disc Brake Brackets
 

Thanks for the compliment :)

You did an excellent job on the Camaro caliper brackets. While you were gone and so many were wanting them, I considered making some but I didn't want to do that until I heard back from you. I looked at your design and tried to figure out a different way to make them, but your design is the simplest and just how I would make them. Do you plan to make any more of the Camaro caliper brackets?

Re: Impala SS Rear Disc Brake Brackets
 

Thanks Captn! I do plan on making some more Camaro brackets in the near future.

Re: Impala SS Rear Disc Brake Brackets
 

I have another run of these disc brake brackets available. :D

61superman I sent you an invoice as requested. Thanks

Re: Impala SS Rear Disc Brake Brackets
 

paypal sent thanks again :metal:

Re: Impala SS Rear Disc Brake Brackets
 

Thanks for the purchase :D.....they will ship out tomorrow.

Re: Impala SS Rear Disc Brake Brackets
 

Great guy to deal with people. And a very nicely made piece to boot.

Re: Impala SS Rear Disc Brake Brackets
 

Excuse my ignorance, but do you need the impala caliper and disc and they just bolt up? Are the discs 5X5 bolt pattern? Sounds like a pretty sweet setup, I might have to do this to my truck if that is all that is involved.

Re: Impala SS Rear Disc Brake Brackets
 

To do this conversion you basically need the calipers and the factory caliper brackets (or cage as some call them), the brake pads, hoses, and the rotors (yes they are 5x5 bolt pattern) and the adapter brackets from me. There are a few other small items you will need, but these are covered in the list of parts I provide with the adapter brackets. Of course you will need the appropriate master cylinder and proportioning valve (adjustable or fixed) to operate the 4 wheel disc brake system.

Re: Impala SS Rear Disc Brake Brackets
 

Thanks for the kind words Josh :D

Re: Impala SS Rear Disc Brake Brackets
 

[quote=Captainfab;3299120]The 98 to 2002 Camaro front caliper is on a 1.25" thick 12" diameter rotor so it would work on the same thickness truck rotor.

The guys on thirdgen.org have worked out ways of putting these PBR calipers onto their spindles that have cast in caliper mount bosses which could be adapted for use on our trucks too.

This caliper could be used on the 14-bolt rear disc conversion that uses the Dana-44 front rotors if you didn't need an e-brake.

Re: Impala SS Rear Disc Brake Brackets
 

Just a FYI GM used same prop valve for the Disc/Drum B-body they used it on the Disc/Disc B-body. Only 9c1 and SS had rear disc not Roadmasters.
