Have you tried adjusting the proportioning valve? The left tire does not lock up? In the winter I did a pressure test each rear cylinder indicated approx psi separately I only had one gage. The valve was rebuilt about 5 yrs ago Which direction would I turn the valve as it sits in the car? While you’re at it, check the size marking , too. If you changed wheel cylinders in the past, perhaps you didn’t get a size matched set. Whenever i did the rear brakes on any of my vintage Mustangs, I always ordered wheel cylinders one size smaller than those the vehicle came with, This stopped the dreaded “rears locking up before fronts” the systems were designed to do.
Bleeding the rear brakes???
EGR or Exhaust Gas Recirculation is a system that takes exhaust gas and recirculates it back into the intake air, this does a few things beneficial to the actual running quality of the engine such as: Reduce Combustion Temperatures which dramatically cuts down on Spark Knocking detonation which is… a common occurance on a high-compression engine such as the LT1, and reduces the NOx oxides of nitrogen emissions caused by high compression which fails emission tests.
Looking face on at your engine, the egr valve is to the left and a bit forward from the power brake fluid resevoir. It is to the left of the power brake booster. There should be an electrical component right on top – it will have the Chrysler logo on it if it is still factory part. If no, like the Taurus, the EGR control valve or motor, which is usually electric, may be defective.
An adjustable proportioning valve plumbed into the rear brake line finishes off the installation. A factory proportioning valve could also be used if you located one from a vehicle similar to yours. We used the adapter, as well as this slick looking master cylinder heat shield on our conversion.
It seems very easy to accidentally grab brake hard when you’re intending to downshift, and that would not be good if you didn’t expect it. Also, I think you want better control of the clutch and brakes separately. Aside from running both front and rear brakes off the pedal, I can only think of a suicide shifter setup. However, I’m not sure what kind of use you can get out of your left arm or if you are comfortable with a suicide shifter setup.
Essentially, you would install a foot clutch pedal on the left side of the motorcycle and run a shifter stick from the shift-shaft up to the gas tank. You can even run the shifter stick clear up as close to the left clip-on as is possible. It takes getting used to downshifting and braking with one hand off the bars, but it used to be a normal setup on stock motorcycles, and plenty of old-school cruiser riders run the setup.
It’s pretty damn fun, but they don’t call it suicide shifting for no reason. I have no spur To prick the sides of my intent, but only Vaulting ambition, which o’erleaps itself And falls on the other. VII BombFactory is offline.
98 ABS Delete – proportioning valve wire?
My power windows don’t move at all! Check the fuse on the power window relay as well as the relay itself for the windows. Also clean the contacts on the switches as noted above – the current for the passenger window passes through the driver’s side switch, so check them all. Can I switch out my 85mph speedometer with a faster one? It is for the same reason that the national speed limit was set at 55mph. However, this regulatory goal may or may not have something to do with the US government giving large amounts of money to the Chrysler Corporation to produce K-cars.
Is this a proportioning valve or just some kind of distribution block? What are the points that stick out from it (one has a wire)? Any other info would be greatly appreciated, including the name of a forum that specializes in Ford brakes.
Making ’em stop is usually not so exciting–that is unless you’ve experienced your quickest pass ever, only to discover that spongy pedal may not get you stopped in time. Many forward-thinkers realize the importance of good brakes and perform upgrades to attain this. Giving proper attention to your brake system is vital. Many times the correct bench bleeding of the master cylinder is an overlooked task.
However, this is a MUST and should be performed any time a new master cylinder is installed. If the master cylinder is not bled, it will take you at least twice as long to bleed the system, and then there’s no guarantee that you’ll have removed all the air from the system.

Oct 19, · The 2 wires connect together to turn the light on The single wire goes to ground to turn the light on. If I remember the 2 wires right, one is power, the other goes to the warning light, the warning light has it’s own ground.
What is Hydraulic brake booster? It runs off of your power steering pump. If it runs off my power steering pump and my pump dies, the belt brakes, or the engine quits how do I stop? Well if you have vacuum brakes and your engine quits how do you stop? On manual brakes, and isn’t that a grunt? So, there is an advantage to Hydraulic brake booster in those circumstances because it has an accumulator for residual pressure in the event of losing the pump.

July 8, is it possible that the blockaged is actually in the proportioning valve? Please try to use proper capitalization. You said you tried at the master and at the wheel cylinders, and the proportioning valve. The clog could be anywhere between the master and the prop valve. Is the prop valve in the 73 in front or in back?
Another big thanks goes out to Steve for helping me understand the process, building the adapter plate for the firewall, the adapter between the HB and MC and bending up the prettiest brake lines from the MC to the proportioning valve!!!
I originally had 4 wheel drum brakes and knew I needed to do something different. Click here for that write up. That was a major improvement. But I wanted more braking power. Next I converted the rear drum brakes to Cadillac disc brakes using a kit from Jeff’s Broncograveyard. I have really enjoyed the improved braking power from all wheel discs, but they were still manual.
I thought about going with a vacuum booster set up, but often I find myself in situations where if the truck stalled I still needed all the braking power I could muster Vacuum brakes give you one pump of the brakes before you get weak brakes. Hydroboost has an accumulator built in and will provide power brakes for 3 pumps after the engine has died.
Then they go back to manual brakes I know what those feel like so decided to do the Hydroboost conversion.
Posts 5, Proportioning pre-WB is done by a restricting valve that is in the rear part of the distribution block, where the fail light switch is mounted. Alternatively you may find that you can remove the nylon valve poppet from the drum valve to give you equivalent brake pressure front and rear but beware – this may result in too much rear brake bias which is bad. The residual pressure valve for a factory, people change things HX is in the master cylinder outlet as I described above, what morcs is talking about is the separate one that was inline with the rear brake line in HQs.
The existing master cylinder can be utilised with a separate proportioning valve simply by removing it use a screw or ez-out to carefully remove the brass seat, remove the valve from behind it, then replace the seat. If you do not remove this valve it will hold the rear brakes on drums require residual pressure to keep the shoes out ready for use, discs don’t.
If you go the WB master route everything still basically applies, its just that the proportioning valve is physically built into the same housing as the master cylinder you will see it has two bores side by side and you can eliminate the separate proportioning valve.
Mar 23, · You can argue all you want. With as many folks as you want. If you feel you’re right you should hold your ground and stand up for it. On a system without the valve.
Hope this doesn’t strike you as borrowing trouble, but here goes: The break happened on a twisty country road up by Big Bear in the mountains semi-near L. Lucky for me it broke on an inward turn, not outward, or I might have gone hurtling down the original Randy Mantooth cliff. If this part breaks, the car basically loses a wheel support and skids to a halt on three wheels and the frame for a skid pad. Think about this the next time you’re doing 90 mph and extolling the virtues of the American V8.
The motors are great, just be sure your suspension is up to the stresses and strains of that kind of duty. Little body damage, fixable. But this time I had a kind of warning. What I want you to know:
