Question:

Hi, Im interested in purchasing the Titan T4750800 surge brake. I would like to know the thread size and diameter of the of the master cylinder cap for the opening for adding brake fluid. The reason Im asking is that Im about to purchase a power brake bleeder that takes specific size adapters. If you could give me this info. I would sincerely appreciate it.

I went out to the warehouse and pulled the same master cylinder used in the Titan model 10 actuator, # T4750800 to measure the opening where the filler cap screws in. Using digital calipers I measured the opening to be 1.56 inches (1-9/16 inches). And as best as I could tell it has 20 threads per inch. It is entirely possible that it is considered a 1-1/2"-20 opening. If you can tell me what the bleeder system requires I can determine if the model 10 is compatible.
