This statement is only true of the "leading shoe". On a typical drum brake, the shoe in the direction of travel becomes the "leading shoe" if the wheel cylinder is at the top of the backing plate. I did a brake job on a '55 New Yorker that had a twin leading shoe front brake; it had two...

If the front end was setup with the FSM specs, the difference between the feel of the FSM specs and the Skosh is significant. Like you, the chassis on the 73 I tried this on would not give me all of the positive caster I wanted without offset bushings. On one side we could get +4º caster, the...

If the "hang" can be felt through the pedal, I suspect the problem is between the pedal and the master cylinder. I can't feel hanging problems through the pedal is the issue is at the caliper. My usual experience is for a single, sliding caliper to hang. This happens when the pins or the...

Tell tales for me have been streaks on the inside tire sidewall and smoke when braking. LOL

Did you bleed master cylinder?

Do you recall what sizes and where they were fitted? I've got a similar problem with the front single piston calipers on the Demon. (It has a Mopar sourced BBP disk brake system.)

I agree with you on the BBP conversion for all of the reasons you gave. IIRC the largest SBP wheel was 5½" wide. Even at that width, Ma Mopar's wheels were known to be a little bit flexible along a vertical axis. This allowed my first Dart to shed wheel covers when cornering vigorously...

X 2 Most of the older power systems were over-boosted, IMO. It's easier for me to tell what is going on between my foot on the whoa pedal and the tires with non-assisted brakes.

IIRC on a single servo (wheel cylinder) system, the leading shoe has a tendency to "self apply". To try to equalize the wear between shoes, manufacturers (Not all, however) started making the front shoe with less friction material on it. Before my time, some car makers (Chrysler was one) made...

Got a suggestion for future reference. Don't take both brakes apart at the same time, just pull the drums. That way there is an example to use as a guide. Exceptions to this are the location of the brake shoes (big shoe in back, short shoe in front) and the location of the parking brake and...

Was leafing through the July 2015 copy of Mopar Muscle magazine, and found a brake resto article on pages 10-14 by Steve Dulcich. In page 14 is a photo of the OEM 10" drum along with its replacement from Rock Auto. The "hat" portion of the OEM rises at an angle, whereas the Rock Auto version...

Yes. But only if we're talking about a 10" SBP drum system migrating from an SBP 7¼" to an SBP 8.75" rear axle, then the only fly in the ointment appears to be the support (backing plate). More important than the 4 hole/5 hole mounting bolts, is the fact that the support for a 7¼" is setup for...

Glad you have some leads on SBP 10" drums. 'Cause IMO, a can of worms would be opened if 7¼ backing plates were used on an 8.75 axle. IIRC, the 7¼ backing plate mounts with four bolts, the 8.75 uses five. Then one has to be concerned about offset of the backing plate relative to the axle hub...

Clips go in the piston and press against the brake pad. The purpose is to reduce rattle and squeal.

A fair number of folks on FABO like PBlaster to deal wiwth rust. I prefer KROIL, as do a minority on the board. Clean it, wipe with a dry towel and put a small amount of either recommended product on the nut and threads that seem to be fused. Let it set overnight.

Sorry, I'd like to be more help. To quote Jerry McQuire; "I need you to help me so that I can help you." How, you ask? Need year, make, and model of car plus pertinents e.g. using a late A-body cable arrangement. I went tooling around Rock Auto using your avatar as a guide. They seem to...

Generally speaking the /6 cars got 9" drum brakes and the V-8 cars got 10" brakes. Since that is the case, an 11" brake drum had to be drilled for a 4" bolt pattern to fit on an A-body axle. Or, the axle has been converted to BBP. It's not a problem unless the front has not been converted...

I'm envious that you can get out and work on the ride when the rest of the east and midwest are hacking out of ice. IMO, start with the easy stuff first. Since you say you replaced a rear wheel cylinder, is it possible that there is a little air in the line? The best cure is to bleed the...

This is my understanding, too. One could order 10" brakes (HD brakes) on a /6 car. IIRC disk brakes on the front would put the larger drums on the rear axle. The best way to tell is to run down the build sheet to determine what was installed at the factory. However, if the car has been in...

There's nothing wrong with the KH disk brakes that were available on 65-72 A-bodies. The reasons for converting these is more often to get the larger bolt pattern hub in order to have a wider selection of wheels. Two upgrades for consideration are going to a drilled and/or slotted rotor. Both...

You'll need a 73 or later UCA and the larger ball joint for the single piston disk brake spindle.

X2 It is the brake adjuster cable. You could get one of another car, but it would have to have the same size brakes for it to work. Although you can get a new one for about $1.00. It may be called a drum brake adjuster cable, and you still need to know your brake size.

The caliper is not carried in the Chrysler Parts catalog as an assembly. The piston housing is 3580 850-1. There are two different single piston, or sliding, calipers used by Chrysler back in the day, both were made by Kelsey-Hayes. The A-body used the one that uses the retainer clip to...

The master cylinder, proportioning valve, and lines in between will need to come from a 67-72 KH equipped A-body. The 65-66 used a single piston master cylinder. Other than the firewall parts, any KH-equipped A-body can be a donor.

Save a few $s by taking the drums into a brake shop or big box parts store. They can tell you what you have and if there is enough "meat" on the drums to turn. AutoZone will turn them for free. Why buy new when you can save the purchase and shipping with what you have? If you have to buy new...

X2 IMO, disk brakes would be a better use of $s.

NTSQD: Thanks for clarifying. Knee point is on the graph based on proportioning valve position and not the use of my leg. I had never heard the expression before. DVO: I'm with Bill Grissom on this one. If you need an adjustable proportioning valve to get the front brakes to lock up just...

What is a knee point? Can someone show me an illustration of what NTSQD is trying to say? A four-wheel disk brake system on a Dart is an example of fabricating and fitting or off-the-shelf kit? I submit that any modification made to a vehicle that deviates from factory practice has elements...

Drum brakes? Does it have the right master cylinder? Both wells should be the same size. I'm adding my 2¢ to those who are recommending new hoses. Look for crimps in the steel lines along the driver side rocker panel area and across the top of the rear axle housing. You'll need to bleed the...

Was rummaging through photos and ran across a photo of what to get from search salvage yards for BBP disk brakes. Not shown: Master cylinder & proportioning valve
