If you have a travel trailor chances are it will be a 10x2 1/2" drum. This kit comes with everything thing you need,. The only two things you will need id a grease gun, and you may need to reuse your lock washers the ones that were supplied were to small . Other then that everything was included. They are self adjusting and I found that if I drove it around a bit and played with the gains it started to respond better. I an about to tow this camper 1500 miles and we will see how it goes.

What is the bolt pattern (PCD) on the brake drum? (for the tire/rim) 5 on 5.63 in / 143mm is listed, but this is not a standard pattern. The other 10x2-1/4" brakes listed have a 5 on 4.5" pattern - which is by far the most prevalent for 3500lb trailer axles.

Answer This Question

Dear Customer, Thanks for your inquiry. 5-4.5, The diameter of the pcd distribution circle is 4.5 inches. 25.4×4.5=114.3.
