Crown 30SCTT:
Brake pad changing procedure

Hi, all. I'm new to this forum and a volunteer maintainer of a crown 30SCTT for a non-profit educational organization (hackerspace/makerspace/community workshop). We acquired a 30SCTT a while back and it has been a workhorse for us. The brakes are starting to squeak, and I wanted to get a look at the pads to see how worn they are. Talking with our local dealer, my understanding is that 8 pads are required to be changed if they are worn.

I took a wheel off hoping to get a look at the pads, but it seems that with this lift the brakes are in the motor assembly. It appears to me there is a plate on the wheel assembly on the opposite side of the wheel that is intended to come off. Unfortunately, the mast is blocking access to remove the plate. It seems like I could either removing the wheel assembly or removing the mast mount is needed to get access to that plate.

I am wondering if someone here knows the best way to get access to inspect and change the brakes on this lift.

Thanks much,

Scott

And since you are a non-profit, that job for a service tech to come out to do is about $1,000

No, you do not rivet new pads on. The rotor gets sacrificed with this brake system. The squealing you hear is most likely the preloaded spring in the middle of those brakes. I wouldn't tear it apart just for those, if it did break that spring.....you can basically pull them out with needlenose pliers. As to when to replace them? On the upper linkage, you will see 3 holes in the weldment. When you adjust to the last hole, it's time to order ALL the parts. All the plastic washers and all

I was able to look at this today, and they are a square disc assembly. By taking a few linkages apart, it was fairly simple to get access to the plate with the brake pads. They actually still have about 1/16" of pad left, and they appear riveted to the plate.

Any tips on riveting the new pads when the time comes?

Thanks much!

Depending on the year of the truck, there are 3 different brake systems for this model. Unplug the battery, remove the kick panel and floorboard. Let me know what brake you are working with. ( drum, disc (like car brakes), or a big square disc assembly

The think the brake drums are under the floor plate on the inside end of the drive motors, more or less in the center of the machine under the floor plate. A big nut holds the drums on and there are brake shoes in there after you take the drum off.
