Question:

I replaced everything on my trailer todo with brakes. Now I use trailer the calipers are sticking. I’ve bled the brakes I’ve checked everything. How tight should those springs be on the master cylinder should they be tight or should they be loose any help would be appreciated.

Expert Reply:

The springs shouldn't need any adjustment and they should feel pretty tight by hand. Did you replace the shock? That's typically what causes the brakes to stick like you mentioned. For a replacement shock for the Model 6 like what the master cylinder you referenced fits you'd want the part # T1242600.

Hi I have a modle 6 actuator. It was seized but I was able to get the actuator cylinder to move in and out. My problem is I can get any brake fluid to exit the actuator to the brake line. Any advice would be appreciated.
