Hi I'm a newbie here. I just purchased a used 3500 Promaster Diesel. Have a question about the parking brake. Is there an adjustment for it. Seems to me it needs tightening up. I have to pull way up on lever to the point it interferes with exiting van. Ouch!!!

My E-brake problem isn't in the the cable pull. There is plenty of tension on the cable and at the handle. I think it is at the E-brake pads. What is the correct procedure for adjusting the E-brake inside the rotor and correct tension of the star adjuster thingy? I don't think my mechanic is going to get this sorted. Thanks

I would think it's a manual feel process. Adjust until they engage, then back off. You want to shoot for 4 or 5 clicks on the handle to fully engage.

Thanks, AZ Van Dream. If my mech doesn't pull his finger out and get this sorted I'm going to ask for a reduced labour charge and attack the problem with a pointy thing myself.

Check to make sure the pivot bracket is not rusted in place under the van right in the middle

Thanks, BKHI. The underside of my Promaster is really clean and rust free. The pivot operates freely. The cables are all very clean and I have never had the winter cable freeze up problem some have discussed.

My mechanic, who is really a good guy and continuing to work on this with me at his expence, contacted a shop that works exclusively on Winnebagos, other RVs and Promasters. My mech described the problem and the other shop said they knew exactly what he was dealing with. We need to get a specific brand of brake drum kit.
Sparta drum kit for promaster.

I haven't heard of them but I said do it. This will be the third drum/pad kit we have tried. I'll update after the installation next week.

A reading from the Book of Mopar: 05 - Brakes / Brakes, Base / Parking Brake / Standard Procedure plus SHOES, Parking Brake / Adjustments...

NOTE: The parking brake shoes used in the drum-in-hat park brake system do not automatically adjust to compensate for brake shoe lining wear. Therefore, it is necessary to manually adjust the parking brake shoes.

1. Verify the parking brake lever is in the released (down) position.
2. Raise and support the vehicle.
3. Remove the wheel mounting bolts, then the tire and wheel assembly.
4. Install a couple wheel mounting bolts to hold the brake rotor in place while adjustment of the brake shoes is made. NOTE: To find the adjuster wheel with the brake rotor on, position the hole in the front of the rotor drum as follows: •Left side – 7 o'clock. •Right side – 5 o'clock.
NOTE: When adjusting the parking brake shoes with the drum-in hat rotor installed, rotating the adjuster wheel upward will loosen the adjustment. Rotating the adjuster wheel downward will tighten the adjustment.
5. Utilizing a hole in the front of the rotor, make a fine adjustment of the shoes.
6. Lower the vehicle far enough to access the interior of the vehicle.
7. Reach inside the vehicle and cycle (fully apply and release) the park brakes.
8. With the parking brake lever in the fully applied (up) position, attempt to hand rotate each rear brake rotor to ensure that the parking brake shoes are working properly.
9. With the parking brake lever in the released (down) position, hand rotate each rear brake rotor to ensure that the parking brake shoes are not dragging.

STANDARD PROCEDURE - PARKING BRAKE ADJUSTMENT

3. Loosen the jam nut (2) and lightly tighten the equalizer nut (1).
4. Using an assistant in the vehicle, apply and release the hand brake lever 5 times to fully seat the parking brake components (1).
5. To measure the force on the hand brake lever, the force gauge must be placed 40 mm (1.57 in) from the tip of the grip, perpendicular to the lever handle (2).
6. Using the force gauge, adjust the rear cable tension by rotating the equalizer nut (1) to achieve 80 N (18 lbf) with the hand brake lever at the fifth click.
7. Re-measure the input force at the hand brake lever at the fifth click to ensure it is still at 80 ± 5N (18 lbf ± 18 ozf ). 8. Holding the equalizer nut (1), tighten the jam nut (2) to 15 Nm (11 lb-ft).
9. Actuate the parking brake to ensure that it is functioning properly.
10. Lower the vehicle.

What they don't show is the return spring is lightweight and easily corrodes, while adjusting take a long look at that...

Anyhow, been a while since the PB adjust routine has been mentioned, keep your shorts on!

83grumman,
Thanks a great deal! This is specific information I didn't have. I will share it with my mech.

That business about needing to get a specific brand of brake drum kit sounds fishy. I can't imagine that's true and we don't know about it.

I am a bit skeptical as well but as long as the mechanic is willing to do it at no additional cost I am willing to give it a go.

I wull report back.
