I see many replacement master cylinders, but none seem to have the slanted top to match my installation area. My system is disc brake Atwood 85736.

Your best route is to replace your entire surge brake assembly as Atwood no longer produces any parts for their brake actuators.

The Titan Zinc-Plated Brake Actuator # T47457207K is going to be your best replacement available. It is specific to disc brakes and has a 7,000lb weight rating while your Atwood 85736 has a 6,000lb. This does have a bolt on design where your Atwood is likely welded on so you will need to cut off your actuator and drill holes to bolt on the new actuator. The adjustable coupler will fit 1-7/8", 2" and 50-mm hitch balls.

We only have one seal that matches the inner and outer diameter you need and that is the part #168233 that you referenced. It may not be quite as wide as your current seal but it still will fit the hub and work well. I have attached a photo of the…

Hi Hans; the Manual Lock Out Kit for Demco DA75 Trailer Brake Actuators #DM93CV is not compatible with the Demco DA70 like #DM72VR. The design is different and won't allow for the installation of the lockout. If you want to add a lockout to your…

If the inner diameter is 1.719 inches and the outer diameter is 2.565 the #RG06-050 would be the closest matching grease seal we offer. You will need a digital or dial caliper for this measurement. The grease seal number you referenced doesn't…
