Re: 6 Lug Rear Discs With 15" Wheels
 

how can I tell which proportioning valve I have? (The more I think about it, pretty sure I just changed the booster & kept the master cylinder.)

Re: 6 Lug Rear Discs With 15" Wheels
 

I have no idea how to tell just by looking at one. The difference is internal. If it is the original to your truck it will be a disc/drum proportioning valve. You can try using that and then installing an adjustable valve in the rear line and see if you can dial in the braking bias that way. Some guys prefer to do it that way.

Hi captainfab did you ever make a rear disc brake bracket with e-brake that will work with 15in wheels

Re: 6 Lug Rear Discs With 15" Wheels
 

Yes I did a while ago. Here is the for sale thread.

Hi,

I'm fairly new to the forum. I have a 71 C30 and while it has factory disc, I wanted to upgrade to larger discs. It has 8 lugs of course. I am upgrading to 18 inch wheels. I have a set of 4 piston brembos I took off of a new Camaro SS that was upgrading to 6 piston. I would like to use these up front with either 13 or 14 in rotors

Do you have anything like that?

Thanks

Re: 6 Lug Rear Discs With 15" Wheels
 

Sorry but no I do not make anything like that. I don't think you will be able to find an 8 lug rotor thin enough to use those Brembo calipers on.

Re: 6 Lug Rear Discs With 15" Wheels
 

Bought your setup and machined axles down and rotors work great. With the 7/16 studs there is a lot of space on the wheel stud openings. At the start of post you suggested 1/2 studs. Any idea on application or part #.

Bracket setup is nice!!

I am officially notifying everyone that I will be on vacation from 02-05-18 thru 02-13-18. I will do my best to get all orders built and shipped before I leave, if placed by 01-31-18. Orders placed while I am gone will be built and shipped in order of receipt of payment once I return. Thanks for understanding.

Will adding these breaks change the track width?

Re: 6 Lug Rear Discs With 15" Wheels
 

Anytime you upgrade to rear disc brakes, your wheels move outwards about 1/4".

Re: 6 Lug Rear Discs With 15" Wheels
 

I have a set of these rear disc conversion brackets done and ready to ship. I had a customer change his mind.

Re: 6 Lug Rear Discs With 15" Wheels
 

If that was addressed to me I am not currently interested. Pushing the wheels out by 1/4 inch will push them out too much.

Re: 6 Lug Rear Discs With 15" Wheels
 

No that was not addressed to you Forest. These are for sale to anyone that wants them.

Not sure why but my calipers don't fit the mounts. It's almost like everything is under sized just a bit. The brake pad itself won't even fit. I'll take some pictures
