Lanos rear brake drum

I serviced the rear brakes on my Lanos. The old shoes still had a lot of wear left but I got some new anyway. The only problem I have is that the brake drum has thick lip on the edge of the drum which makes adjusting the rear shoes difficult as the edge of the drum wont slide over the shoes. There is very little wear on the lining surface of the drum and it looks like the edge of the drum is caused by corrosion that has built up over the years on the area of the drum where the shoes do not make contact. Is it ok to grind down the lip of the drum so it is smooth and level with the lining area?

i did that on my rear drums in the Nubira, so i guess it will work good with u on the Lanos too, but watch out and dont adjust the brake shoes so wide more than needed or u will find out after installing the drums that they are heavy when u try to rotate them.

I used a dremel to grind the lip down and I can now easily adjust the shoes so the drum fits over without any problem. I cleaned up all the self adjusting mechanism but I find that they never work properly and still need to be manually adjusted by turning the adjuster screw until the drum just fits over the shoes without binding. My foot brake is much better and doesn't travel as far as it did before so there must have been too much gap between the old shoes and drum. I adjusted the h/brake and that also works much better with equal pressure to both rear wheels.

did just that on my lanos... got no tools for it so i took off the drum, install it backwards on the front rotors then started the car and put it in 5th... used an abrasive sand paper and after a few turns the lip was gone.

lol, that's a great idea. I'll remember that one for future if I need to do it again. You probably get a more smooth & evenly round finish doing it that way as the same amount of abrasion pressure is applied all around the lip.

indeed... you only need a spacer to clear the caliper on the front brakes system and try to balance the drum as much as you can to avoid it from wobbling when it is spinning.

wear a thick pair of gloves to protect you from the heat generated from the friction... the results are the next best thing to having the drums machined.

great idea really, for me i just sent the two drums to the machining shop and got them back done after 30 minutes, but i love ur idea more cuz its self done without machining
