2004 Sunova Workhorse Brake Master Cylinder Fill Level

[Tim Nadaud]

Hello, I have a 2004 Itasca Sunova 27C P32 Workhorse chassis 8.1 Vortec engine with a 4L80E transmission. I have recently replaced all four brake calipers. My questions is: how much brake fluid should be in the master cylinder? My master brake cylinder has no fill line markings. Any info would be greatly appreciated.

Does it look like this?



Anyway, approx. 1/4" below the top is full, 1" would be the minimum line. The lid has a special gasket with bellows that drop down to fill the air space to help prevent brake fluid from absorbing moisture.
BTW, brake fluid should be flushed and replaced at least every 5 years for that reason, moisture in brake fluid.

Ray,
Mine has a black plastic cap with four retainer clamps, which are part of the cap. Hope this makes sense. Thanks for the reply.

If it looks like this one, it has a long oval on this side with a dot in each end of the oval, indicating full and minimum. https://www.summitracing.com/parts/a...custom-chassis
I wouldn't buy from them, that's too much money.
