I am putting brake lining on the steer axle of my truck.
When I put the lining onto the the anchor pins I have to actually Hammer the lining down over the spider to sit on to the Anchor pins.
When I say hammer I don't mean Hammer like Sledgehammer but I do have to tap it in. No way I could just set it on there by hand.
I thought everything is supposed to be loose and free. I did sand it down and it's a little better, but it's still tight.
These are the Linings from Freightliner that they say my truck calls for.
What do you think?
Brake lining right or wrong

I think you need to post a picture was there a lot of paint on it ?

It will likely be ok. Are these new shoes or reman? The anchors of the shoe table will actually spread and stretch open over the life of the shoe, so a good snug fit when new is what you want. Reman shoes are ussually reshaped at the anchor. Make a couple good brake applications after assembly and readjust to make sure everything is seated good.
What brake are you working on? -
They are relined Meritor Q Plus shoes for the steer axle. -
Yep, it’s normal for that to be right there. You want that snug. I give each a smack with a hammer to make sure there set. The pivot pin itself is what you want to move in the bushing. Make sure the pins slip in there. If they are rust solid the pin and bushing should be replaced. Make sure the new ones slip free.

I've noticed that sometimes with a new pin and bushing that when you put the new pin in it will slide in and out but when it gets to the end it's a little bit tight or it'll spend tree but then it kind of finds a high spot or something. Like it isn't just completely free to spin all the time.
Do you guys encounter that also? -
Yep, sometimes it’s just a bit of rust under the bushings. If you can get the pin 90% in by hand, you can usually bring the pin in for the other direction 1/2 way in and hammer around on the pin to “fit” the bushing. Do that from both sides till it’s a slip fit.
If it’s too tight or I can’t get the pin to free up, I’ll remove the bushing, use a small brake hone to clear just the rust, and install a new bushing.Dino soar Thanks this.
