drum brakes...enough said...


Recommended Posts

I have been fighting with the drum brakes in my 88 2wd with the d35 for a week now. Ive only done drums a couple times on my old trucks (94 f150 and 99 Dakota). THe passenger side appears to be fine and everything when together like it was supposed to and no issues there. The driver side has been the devil. The front shoe will not seat where it is supposed to and after having the self adjuster and bottom spring come lose while driving I have it all put together, adjusted all the in and now it is dragging so bad that when o got 2 miles down the road to Walmart the driver side is smoking. Am I missing something here? I've never had issues like this.

Yeah, the shoes for each side have a "front" and a "rear" for lack of a better term. That would cause your issues as would a problem with an e-brake cable or the adjuster hanging up. I would also be concerned about how much trouble you had getting the shoe to seat. It has perhaps popped out and will not return, thereby pressing against the drum. Where a sticking caliper would cause these symptoms on the front I have never heard of a wheel cyl causing this.

I have the shoes on right. I only did one side at a time, the short shoe is in the front, driver side has a new parking brake cable and wheel cylinder, new hardware and self adjuster. Compared the old stuff with the new and it all matches up. I can get the front shoe to seat but it doesn't stay there.

I can't visualize what this means. And the Bendix drum brakes that AMC used are (IMHO) infitely easier to work on than the accursed 9-inch Chrysler drum brakes.

 

Post a photo of where the front shoe won't seat.

What does "popping up" mean? Did you use new attaching hardware, including new hold-down pins and springs? Are you certain that the spring retainer cups are properly seated at 90-degrees to the head of the pin?

 

If you bought new hardware, are you sure it's for a Dana 35? The D35 brakes are 10"x1.75". The D44 brakes are 10"x2.5". Hold down pins for the D44 brakes are too long for the D35.

I have the right pins, everything is on like it should be and popping up means exactly that. A virtical movement upwards form where it should be. The top of the shoe should sit on the peg right above the wheel cylinder. It doesn't want to stay there.

Your wheel cylinder is shot, the pin will not retract on that side.

 

I experienced this on my old D35.

They are $10 at OReillys.

If you have the correct leading and trailing shoes figured out (short liner leader, long trailer) and you got the 1.75 vs 2.5 on both PINS and SHOES, then check to see that the parking brake lever and its retainer clip are on the trailing shoe top hole.  I've been running mine without the spring washer so I don't think that could be a problem.  A lot of times the parking brake cable guide, again on the trailing shoe, will pop out of its hole when you mount the trailing spring.  I have to glue mine into place so that I get a good spring mount without pulling the guide out of the hole in the shoe.  When the parking brake strut, the wheel cylinder plungers, the shoe springs and the cable guide are in place the shoes should automaticly snap into position.  I CAN'T IMAGINE ITS POSSIBLE TO INSTALL A SHOE UPSIDE DOWN...  I can't even imagine doing the initial adjustment and getting a drum on unless the shoes are in position.  The parking brake and adjustment stuff easily go in after you get everything else right. 

 

If the shoes aren't riding up on the backing plate sliders but are actually down between them and the backing plate flange how did you get the drum on?  That flange rides in a groove that goes around the bake drum?
