I use Firm Feel's carbon-metalic pads, and love them. I was going to attach a link, but don't see them on their site anymore. I sent a notification to find out if they are still available. It is my understanding that high performance pads require significant warm up time before they reach their...

Email Doctor Diff. He is the most knowledgeable man I ever met regarding this swap. You may be able to PM him here as well.

Typically, I've had to tighten. loosen and re-tighten the banjo bolts a half dozen or more times to get them to seal correctly. I repeat the process until the banjo stops advancing farther into the caliper. It usually threads in just about a 1/4 to 1/3 turn more than if I just tried to tighten...

I always bench bleed master cylinders in my vice and tap the MC with a small hammer to help dislodge any small air bubbles. A large phillips head screw driver works well to fully depress the plunger too. I also tip the MC nose down a few times to help displace the air. If I come back to it about...

Perhaps, using loctite orange on your nuts and bolts would be better on brake hardware.

Tighten and loosen the banjo bolts half a dozen times and you will find the bolt rotates farther in as the parts seat & mate together better. it's somewhere around 15 to 20 ft lbs for the banjo bolt.

What are you using up front to match these big rear brakes? Maybe 13" with Viper Calipers or something massive like that? All the Mopars I have ever owned tend to lock up the rears way before the fronts break loose. I've had to use smaller rear wheel cylinders on the rears to "calm" them down...

Why do you need such big rear brakes? I have Dr Diff's small rear econo kit brakes, from a 2005 Mustang Cobra I believe, and they match perfectly (front to rear bias) with the 11 3/4" Police Taxi fronts I got from him. No need for any adjustable proportioning valve at all.

Avoid them, and call Dr Diff instead. I helped a buddy try and install them on his GM convertible. They bolted on with some issues on alignment, fit and then we found out they sent the wrong power booster bracket. They looked good on paper, but don't live up to claims or even function properly...

On one car, I had to put the washer's between the rear end housing adapter and the caliper bracket. The caliper does "float" to some degree to equalize the clamping force, since the piston is only on one side of the caliper.

I have Dr Diff econo rear discs on both my Mopars. The Mustang calipers adjust by turning in and out the caliper piston. I push back the rubber boot and carefully turn it with channel locks although there is a special tool available as well. Most chain auto parts stores lend it to you with a...

The only two guys I am aware of that could more than likely give you the correct answer to the bias rate the two brake packages you are talking about are Dr Diff -aka Cass-, and AndyF. It sounds like you are already aware that using an adjustable proportioning valve is generally only a band-aid...

Good for you for tackling the job. I used Dr Diff's econo 4 wheel kits to upgrade the brakes on both my Mopars. One is manual and the other power assist. They both work great, and Dr Diff is an incredible source of knowledge and advice. Be sure to keep an eye on the hardware and fastener...

Measure the distance between the two connections you are trying to plumb the line for using a measuring tape. You can also use a piece of 40" wire or cord that follows along the correct routing to see if it will fit between the two fittings properly. Or, buy or borrow a tube flaring kit to cut...

Which manual and what still rubs on the caliper bracket? Post pic's please.

No, but you are close. If you loosen the nuts holding the master cylinder onto the booster, does the piston retract farther? If so, you have extended the pushrod too far.

Be sure to shim the rear calipers, so that the opening where the pads pass through the caliper is centered evenly in the pad opening. I used a grade 8 washer to center mine, although any steel washer should be sufficient. Also, check to insure that the rotor is not being held off it's mounting...

I had to enlarge the holes in the rotors to get my rotors to sit flush on the flange for the same reason. The center register hole kept everything lined up though. Not a big deal. I used a hand drill and a step drill bit.

I had the same leak. Turns out the rubber gasket is just a bit smaller than it should be. It barely covers the sealing surface. It's just undersized enough that if not positioned correctly, the gasket won't seal the surface on one side or the other. My solution was to cut off the two tabs that...

Also, a buddy who's an Aircraft Certified Mechanic gave me the following tip regarding making flared ends. Polish the end of the cut tube before flaring with a small file and then some emory cloth. That will remove the spots that can lead to the line splitting at the stress risers.

There's nothing wrong with turning those parts, especially if you have the equipment. It's rare to see any brake lathes in shops anymore though. I upgraded my front discs to the 11 3/4" Police/Taxi rotors on the front of both my '68 A-Body & '70 E-Body. I run Doctor Diff's Econo kit rotors on...

I didn't know people were still having their old rotors turned. I just use a new rotor and replace the races with the matched set that comes with the new bearings. If I'm just upgrading pads, I sand the rotor face to deglaze it, spray it off with brake clean and install new pads. I also seat...

Here's a link to DPI and an excerpt from their part description w/ a picture. Notice how the valve is oriented in the car to allow efficient bleeding of any trapped air pockets in the line. Lock Resistant Brake System (LBS) "Lock Resistant Brake System (LBS) The LBS was originally developed...

Cass, AKA Dr Diff, is a great man to do learn from and do business with. He is VERY knowledgeable and helpful. I installed Firm Feel's front brake pads in the big single piston calipers, and used the Mopar 11 3/4" Police/Taxi front rotors with Cass's rear Econo Kit. That rear kit uses 2005...

Mopars are known to have overly sensitive rear brake lock-up issues in a panic or hard stop. Proportioning valves are a band-aid for poorly matched brake components. In your case, seek the matching valve to your brake parts. It won't really help rear anti-lock, but at least you'll have matching...

I've never tried the ones you've listed. What size wheels are you going to run? Wilwood's are ok for a track car, and a limited weather use street car but they have no dust seals to keep dirt and water out of the caliper piston bores and can be pricey. They are light, perform well and look...

Run one with <1" bore and you won't regret it. Also, spend the money on braided flex lines. Dr Diff can set you up with both items. Its money well spent on a critical system. You will enjoy the difference every time you use the brakes.

If you want great brakes that won't break the bank and will be upgrading to the larger bolt pattern with the 8 3/4", call Dr Diff and run the 11 3/4" Police Taxi rotors up front with his rear Econo-kit that includes 2006 Mustang Cobra R disc's and calipers with the emergency brakes built in...

Time to back-half the car. Don't you have problems scraping the undercarriage while driving the car on the open road? My car's stance is no where near as low and I still scrape stuff every now and then. I don't see how you can even go over a common speed bump without getting hung-up.

I got the master cylinder from Dr Diff. It's the <1" bore cast iron version that works for 4 drums or 4 discs. No residual pressure valves were in it.
