## Customer Reviews

### ⭐⭐⭐⭐⭐ 







  
  
    Always put the smaller shoe to the front.
  

*by B***H on Reviewed in the United States on January 18, 2023*

I had loaned my trailer out and there truck was not wired the same as my truck so the breaks trailer brakes were on full for miles and got really hot, so it was better to just install new ones. And these were so easy to do.

### ⭐⭐⭐⭐⭐ 







  
  
    Great price
  

*by E***T on Reviewed in the United States on January 29, 2023*

Fit perfectly, great price, it was way harder to remove the old ones than to install the newones

### ⭐⭐⭐⭐⭐ 







  
  
    Easier than I thought.
  

*by R***Y on Reviewed in the United States on November 2, 2022*

Just unbolt the old back plate and bolt in the new and voola! Although my application was a little more involved because I went from hydraulic surge breaks to electric but that had nothing to do with the product.
