LS 400 1997 parking brake

Recommended Posts

I'm replacing all rotors and having calipers refurbished but I have come up against a real problem with the parking brake I cannot remove the rear rotors, the shoes on the parking brake are sticking slightly when turning the rotor and when trying to remove the rotor it will only come off so far and it must be the shoes preventing it. I'm thinking the adjustment must be automatic as I cannot find an adjuster to ease them off, the cables under the car are pretty slack so don't think they are a problem. I have put the rotor in the six o'clock position with the access hole lined up but cannot see a cog, on one rotor I can see a spring and washer is loose in there and was able to pull out the pin which the spring held on from the rear near the hub. Just cannot think how to loosen off the shoes as brute force will only make the situation worse. Thanks.

I'm going to take a closer look at where the adjuster should be as there surely must be one I'll have to get a bright pencil torch on it as I could only see the bottom spring before.

Adjuster should be at the top, it is a PITA to see it through the hole in the drum where the rubber bung normally fits.

If you can't free off the shoes there are 2 threaded holes 180 degrees apart where you can screw in a couple of bolts that will push the drum off the hub.

Hello John.

I have a 1998 LS and the adjuster cog is located in the 6 O'clock position.

I agree with Steve, it is a real pain to see, even when using a torch.

 

Steve.

Here is what it should look like when you get it all apart.

The bottom hole in the hub is where my adjuster is located.

I can feel the spring but not the cog is it above the spring?

I have it now thanks for all your help I was feeling around for a small cog with small gaps between the teeth but they are quite large, simple when you realise where and what it is!

Wow Steve I am impressed by you bravery working over gravel, the amount of times I drop things and have trouble finding them is shocking. :clapping:

Yes, I do not work on gravel for the same reason!

If I had to, I would put some old carpet down over the area where I was working.
