Getting new drums and shoes put on the front rear axle of the truck. I only got fifty thousand miles out of them. The rearest axle, that was put on at the same time as the front will probably go 100,000 miles, still plenty of pad left.

Now, my mechanic called the parts shop to order the new shoes and asked them about these shoes and should he switch to a different shoe. He was told that operations similar to mine some shoes are being changed at 28000 miles.

I just came from the shop and my mechanic found that my cans were different sizes, we also replaced the slack adjusters because they weren't functioning properly. I hope this solves my problem. The brake shoes were worn much differently on the front rear axle as well. One set was down to rivets and the other side probably at 1/3 of the original size.

What kind of miles do you guys get out of a set of shoes and do your front and rear axles wear evenly or does the front (rear) axle tend to wear faster?

 

I just had my brakes done 2 weeks ago RC. They had 245,000 + on them and were still at about 30% of pad thickness left. My problem was that 2 wheel seals started leaking, both on the right side...so told the shop to do all 4 positions, including the drums.

I wonder who the re-manufacterer was on your old shoes. I think that and the material they use, is the biggest part of the wear issue. Some companies go with cheap-o just to save a buck now, instead of buying quality and saving 6 bucks later.

 

oops. I should have posted that my current operation is semi to mostly local, so I probably won't get 245000 out of a set of pads but 28000 miles is just wrong OTG and even 50000 miles is suspect but we'll see if the new cans and slack adjusters make a difference.

The shoes are from............... China issedoff: I saw it printed on the side of the shoes yesterday, but like I said the rear shoes look good and it's the same shoe as the new one and the old ones that we just pulled off that were worn out so.......... :bigthink: I dunno??

 

Don't bother with that China ****. Use genuine parts only!

 

Just turned 500,000 and still on the original parts...around 30% left. Front drive is wearing faster than the rear.

 

depends on the hardness of the lining.there is 21000 lb,and 24000 lb lining,they also make 31000 lb lining,which is hard on the drums,but wears like iron.

it will tell you the hardness on the side of the lining,if it is still visable.do a search for eucklid .com,they do a lot of brakes and have charts which shows you a lot more than i can tell you.

 

There was a good article on a brake pads in recent Land line....Sold my old truck, with 962,000 miles, with original brakes on a drives, only replaced steer axle once, at about 400,000 miles. Current truck has all original yet at 470,000 miles.....Not really a cost to cost either, a lot of North East including NYC, also a lot of secondary roads, with the traffic lights....

 

Guess you must have always been pulling company trailers and using the johnson bar most of the time, eh???:smokin:

 

are you comparing steer brakes to rear brakes ?

Anyway, bad slack adjusterswill cause your problem. also check the relay valves that it is pushing air evenly to the chambers.

but new slacks and regular brake adjs ( even with auto adj).. do it evey month at least...they take less than 1 min to manualy adj them.
