I have 11 inch rotors on the front with single piston, will I have to change anything other than calipers and pads to upgraded to a 4 piston caliper?

**Maybe this is what I need ---------------

If this is "what you need" then you don't have enough vacuum like you stated you do in your previous post. Just sayin...

VW Audi part number 8E0 927 317 can be found in 2001-2005 VW Passat, 2002-2005 Audi A4, 2000-2004 Audi A6.  It is a vacuum pump made for the brakes and can be easily wired in.  I'll be looking at the junk yard for one of these next weekend when I go after a transmission for my Cabrio.

I cant find the specs now, but when I started looking I found something that said it should pull 20 inches at sea level (Less at altitude), but should at least be enough to work the brakes since that is what it was designed for.  This is listes as an assist pump, so you might still need the vacuum from the motor, though the electric car builders use them and don't have any other vacuum sources.

As for the noise?  Maybe I can make an insulated box that will help quiet it down.

At any rate, $200-$300 at a parts house, $10-$20 at the bone yard.

  A healthy cam and 3" exhaust will take care of ANY noise issues....

Because, there is no way to have owned a Charger without having some cool stories to go with it.

Do you have pictures of your current set-up?

Do any of the brakes lock up? (Have you don a Dan from Fantom Works brake check)



Heyyyyyyy***THANK YOU THANK YOU  for that suggestion of the Summit Racing® Electric Vacuum Pump--installed this on my car over the weekend & POW!!! We now have brakes!!! Much much better--( the rear drums can STAY!!)  --without having to spend thousands on 4 piston calipers, slotted rotors-- ect ect------------------------------We put this little Marvel under the battery tray & it's really a great improvement ---------------This unit is not noticeable or noisy when the car is running at all & appears to be very sturdy. It fit well under the tray & I've bolted it right to the fender wall with the supplied stainless nylock nuts & bolts. I really would never have considered going this route but am sure glad you mentioned it---so much easier than replacing the rear drums and heck --it wouldnt have done much as I only had 9" of vac pull --

Either the kit you bought is crap or they aren't working correctly. Power brakes? If so your cam is probably not making enough vacuum to operate the booster giving you a shit pedal.

How do you install an electric vacuum pump? Does it go right to the brake booster?

 Also what is that canister for under the battery tray which has 2 vacuum lines.

The electric pump is just a helper pump.  The original vacuum canister is for the A/C controls.

Hooking up the electric pump I plan to segregate the brake vacuum circuit from the motor.  Pump, A/C (when I finally get it reinstalled), brakes, and vacume canister.  Im looking to use a larger canister than the stock one under the battery.  After it is installed and wired using a relay and this vacuum switch...



https://www.summitracing.com/parts/ssb-28146sw?seid=srese1&cm_mmc=pla-google-_-shopping-_-srese1-_-ssbc&gclid=CjwKEAjws-LKBRDCk9v6_cnBgjISJAADkzXeFdZg6aEpmur5jZT8l5HVtDP0t7ki5QW6b-L1wI_R4xoC1i_w_wcB

After that is assembled I will be connecting it to the engine vacuum with a check valve that will allow the engine to supply most of the vacuum to the circuit, but not allow any of it to escape back to the engine.  

The way it works is the engine vacuum (in my case only supplying 10 inches) will give me half of what I need, but the electric pump will turn on and charge (if you will) the system up to 18-22 inches.  Once it reaches that it turns off and does not come back on until the system dips below 18 inches again.

My hope is after this that my brakes will finally work as they should.  They do work right now, but the peddle is stiffer than it should be because of the lack of proper vacuum (Due to my Torquer manifold from what I understand) and the car takes a little longer to stop.
