Rear Disc Brake Remorse

[rklein71]

Is anyone out there having rear disc brake conversion remorse. The Cadillac Eldorado calipers are a major pain in the butt. The bleeders are not located on the top, the adjustment for the parking brake is very difficult. Kind of wished I had stayed with rear drums.

I, too, have heard more stories of regret than joy putting rear disc on the e-body (and b-body)

four disc, all-around, seems cool and modern. but in terms of braking force, it isn't warranted. Unless you're towing a boat, or something.

Yep I have done it, never again unless I'm building a 200mph car, drums are fine for the rear in any application I plan on using. I did a willwood set, $$$ they worked fine but for the money, not really worth it.

Knowing that the rear brakes don't do near as much as the front brakes, I never considered going to the expense of swapping. I did source the parts to go to the bigger 11" drum brakes from the salvage yard and upgraded to the bigger drum brakes. I also put in an adjustable proportioning valve.

Some of the rear disc brakes kits for the 8 3/4 use Cadillac calipers as they have a nifty built in parking brake. But they cause other problems as well. Drums in the rear work just fine for me! And remember the first Dodge Daytona to go 200+ mph had drums in the rear!

Many systems eliminate the tapered roller brgs & force the use of green brgs which is a Huge NO for me , they can interfere with the rear sway bar in many cases And as above are not really warranted unless you are on the brakes hard a lot such as autocross .
The first place I would look is Scarebird using cheap parts to create a system or Dr Diff for more functional rear disc pkgs if you want rear disc .

From another post.

The Wooden Roller coaster feel can be reduced with air shocks and extensions can be placed on the top side of shock and reduce air pressure. Worked for me did a lot of highway driving. How ever it does change front end alignment a little bit. When done with suspension (put the big weenies on 11/16 tie rod) steering,brakes(There is so much more to be gained with larger brakes on the front 11 3/4" rotors.Or bigger! Best money ever spent.(70-80% of stopping power comes from the front).ABS rear would be the most beneficial.( Articular using Dakota rear ABS system and a Ford 8.8 tone ring.)I have had 2 1/2 sets of hens teeth for decades and yet to put them on because of Green bearing. I would have thunk there would have been a fix for that by now?I agree the rear disc look good if you can see them.and other factors easier to maintain and cool off quicker in racing conditions. Drum brakes done right last 100k miles.When the Parking brake is set the adjuster adjust the rear drums.// I would have it Aligned. Aligned with the stance you want. check air pressure and bumper height for reference for street or strip. A little more on pass side helps with hooking up on track.If you have two singles shocks.//Vibration at high speeds. Could be a number of things U joints. drive shaft splines worn,loose saddle or stripped.Weight has fallen of drive shaft. Worn,broke loose shocks steering components box rods,bearings,bushings.Bent rim tire has busted belt.Tires worn and out of balance?// The previous items are of safety concern that should be coincided. Just my opinion and maybe others. There are knowledgeable individuals here. I wounder what the combined experience is of the members? I understand personal preference rules over all.Game Set and Match! I didn't want to touch the rear.that could touchy and I would get slapped!!!

What about the jeep grand cherokee (93-98) rear disc?
The caliper mount is a backing plate with inside rotor park brake.
Standard bolt pattern, and regular park cables. Bolt on to 8 1/4" and 9 1/4"
Some mods for 8 3/4.

Anyone ever measure the weight savings?
How much heavier are drums, 5lbs per side?
