Is there anything in the aftermarket world thats actually plug and play like they claim? One of the upgrades i decided to make was go to a power disc/disc brake system versus the manual drum/ drum setup. I bought my brake lines from inline tube and the master cylinder, booster, proportional valve, front and rear disc kit from Pirate Jacks. The issue im having is that not all of the flared fittings seem to match their corresponding holes on the prop. valve. One in particular is the line leaving the front driver side. I posted a couple pics of it below. I was able to find a diagram online just to verify which line was suppose to go where. Anybody else ever run into this bs?
No there isn't. The aftermarket one size fits all, right out of the box, direct fit, improvement over stock, new, improved, better than stock, five minute, just bolts right on - is a bunch of crap! Been in your shoes and have all kinds of aftermarket crap on my shelf that I can't use, including brake parts, took me a while but I use original GM stuff whenever possible.
I have front disk and rear drum manual brakes on my 68. I did not like the front to rear bias that the factory GM proportion valve had so i installed an adjustable proportion valve. car stops much better and evenly now. Their are many GM proportion valves that are built for different model GM cars. They are not all the same.
That looks almost the same as the valve I bought about seven years ago, it's bee a paper weight ever since. l also bought a replacement after market disc set up, rotors, bearings, seals, splash shields, brackets, calipers, pads, etc. I used the rotors, nothing else would fit. Even the pads and the dust cap to go over the spindle nut are junk. Even the two cotter pins were the wrong size.
l also have front disc rear drums, l use a GM single piston set up off a 69 Camaro, just replaced the rotors and pads. My master cylinder is a manual non power drum drum unit, l couldn't get the proportioning valve to fit so l just run without one.
l think the threads in my valve are the same as the one in the diagram you posted, if it works for you you can have it, not doing me any good, but might be the same as the one you already have.
Yeah i believe its the same as mine also, all of my female ports are the same size as the diagram pic i posted above which tells me that they put the wrong size fitting on a couple if the lines. For example, the rear brake line has a 7/16-24 fitting and the port that it suppose to go in has 9/16-18 threads. The front driver side line has a 1/2-20 fitting but its suppose to screw into the 3/8-24 port which sucks because now im gonna have to take the rear one piece line back off and get new fittings put on which wil require me taking it somewhere that can flare ss tubing
Had the same issue with brake lines on Jeep CJ. Wouldn't fit an aftermarket brake booster. Took them to a guy and he made up fitting on the brake line with the correct connector. The Jeep off road specialty shop guys had the connection.
I bought all my aftermarket stuff from right stuff (https://www.getdiscbrakes.com/) and I had the same problem (Same proportional valve) and none of my lines fit either. They told me that if using the aftermarket set up I had to get the lines that fit and work with those aftermarket proportional valve which I did and everything fit. I had already bought new lines from them but none of the info was stated anywhere. So I actually replaced my lines twice. If you do this do not buy the stainless. While nice to have, it is too hard to get into tight places. Also, get the front to rear line that is two piece as it is a lot easier to get in then the long one piece.
Yep, inline tube told me that the lines i bought from them were actually made to fit a factory disc firebird which supposedly had a distribution block and some sort of hold off block which had the correct female threads for the lines i bought. I never thought that depending on if your car was factory disc or not that you would get different size fittings. More time, more money as usual
You all should be able to buy reducer/adapters to go from one size to another. The parts houses all have the on one of those rack setups with flare fittings made for brakes. You may have to go to a couple different stores to find what you need or probably can order from Speedway.
