...The 3rd pump will actually skid quite a few rocks. I know sounds like air in the system. I have a 15/16 bore master, adjustableproportionvalve for rear and distribution block. Just checked a few minutes ago. Calipers seem aligned. The hoses on the rear have A LOT of movement. Both hoses on...
that unit is sold by inline tube and if it’s anything like the rear proportionvalve they sell i don’t think you will he happy with it.
Take the advice from @Stanton and just purchase an adjustablevalve and install in the rear line between master and rear cylinders.
‘71 Charger with 4 drums converting to disc in front, drums in back.
Do I need a metering valve as pictured in the service guide?
I got:
A 70-71 Mopar E B body Disc Drum Brake Distribution Brass Block ProportionValve
An AdjustableProportioning Vale for the rear.
A bendix style dual...
...( 15/16' bore manual ) and of course made up the new brake lines I keep the 10" drums in the rear! I did use Wilwood adjustableproportionvalve. The spindles have the same dimensions (angles at the ball joints, height, etc.) so all the front end parts like each other and work a normal. The...
...cup and in the axel tube. Adjusted the endplay as the FSM advised. It is a little cooler but not much. I then put an adjustableproportionvalve in the rear brake line. Now I an getting a little heat at the front brakes. That passenger rear is still hot. I am thinking that the bearing is cooked.
Disc/Drum are what has the residual valve. Designed to keep pressure on one section of the brakes. If this is removed and the distribution block has the shuttle valve removed then you are able to use an adjustable manual proportionvalve. The stock distribution valve is not designed for 4 wheel...
Okay so my master would have originally had a residual pressure valve in the front port (rears) that should have been or needs to be removed. I would tend to think it was removed because if it was still there wouldn't it be causing the rear disc brakes to drag/overheat? I think the aftermarket...
Started to fiddle around with brake lines. Inherited parts from a stainless kit that I'll try and get use of.
The passenger and driver side line fit pretty well.
But the threads into the proportionvalve wasn't correct. The valves female threads were 7/16" and the lines were 3/8"?
Well, anyhow...
I just read this:
**********************************************************************************************************
The reason aftermarket "proportioning" valves (that are nothing more than pressure regulators) are inappropriate is that they do not perform the multitude of functions a...
...here, I’ll try it. After that, if I still don’t have a pedal then the new combo valve from Dr. Diff, which is a disc/drum set up, will go in. If that doesn’t work, well, I’m out of options unless I plumb all new lines with a Wilwood adjustableproportionvalve. I know that will fix these...
...B-Body ball Joints). So got two new calipers and pads. I use a 15/16th bore manual (two hole) master cylinder and Wilwood adjustableproportionvalve. A lot of climbing under and out from under car, wrong size tool, need different tool. torch to heat bolt, new bolt, etc. etc., Gravity works...
What I've learned is that you should use a proportioning valve if you're going with a disc/drum combo, with power or manual, to limit the pressure to the rear drums, so you don't lock 'em up and spinny-spinny.....I'm still using my factory manual drum valve (it's really just a distribution block...
Hi All,
I am installing a news set of brake lines and willwood adjustableproportionvalve and I've realised I have the front to rear line that has provision for the factory valve/block piece. So while I've have the willwood adjustableproportionvalve in the place of the front factory...
...and keep the rear brakes from locking up early.
In short, if you're doing this conversion, you might plan to plumb an adjustableproportionvalve in line to rear brakes. You can always open it up, but most likely you'll need it to adjust bias.
Here's a good start for reading...
...I've done this on my Duster, Valiant and now the Belvedere:
Kept the stock brake distribution block, never used an adjustableproportionvalve.
Wilwood disc fronts and factory drum rear.
Never had an issue stopping. No grabbing or fading.
Drove these on the street and on the strip.
Belvedere...
