Herlache Truck Lines LLC Posted April 24, 2019 Share Posted April 24, 2019 Need help! Bought a 2020 Mack Anthem, we've had it for 4 weeks and the brakes are squealing so loud that I can hear it while i'm on the phone with the driver. Condition exists mostly at low speeds less than 15mph but has also occurred at higher speeds less frequently. I have asked the lead mechanic at my local shop and his instruction was as follows: "I just spoke to your driver. I explained to him about the steer brakes, that they are Reduced Stopping Distance Brakes (RDS shoes). "The brake material is so hard and aggressive, they have tendency to squeal. We where advised from the brake manufacturer that it will take some time for the brake shoes to burnish (wear in) into the drums. Any questions let me know. Thanks" Mike Pierquet Service Advisor My driver has tried to burnish the brakes by depressing them hard at low speeds with a load on many times and continues to try it daily but the condition of a loud squeal still persists. We currently have 10K on the truck, wondering if anyone else has experienced this condition or can advice on a remedy. Hope to hear from you soon.

Maxidyne Posted May 29, 2019 Share Posted May 29, 2019 Sounds like Volvo did a "work around" with the high co-efficient linings to avoid having to fit bigger brakes.

Mario camalieri Posted March 31, 2021 Share Posted March 31, 2021 I have a 2021 anthem with 8000 miles Squeaks every time I put the brakes on..! Quote Link to comment https://www.bigmacktrucks.com/topic/56883-mack-anthem-brake-squeal/#findComment-471795 Share on other sites More sharing options...
mrsmackpaul Posted March 31, 2021 Share Posted March 31, 2021 Are these a disc or drum brake ?? I have no idea disc brakes on trucks On cars if the shims and spacers aren't installed in the correct sequence they will squeal and sound like steel on steel Thinking that big trucks maybe the same Even if it's drums the outside edge of the shoe can drag on the drum if they arent spaced or installed correctly Paul Quote Link to comment https://www.bigmacktrucks.com/topic/56883-mack-anthem-brake-squeal/#findComment-471797 Share on other sites More sharing options...
