NO BRAKES 83 JAG?

Question

83 XJS Not losing fluid, fluid clean, pedal goes to floor no brakes. Pads new, rotors could use cleaned up (they are smooth but have an edge thicker than a finger nail) guy that did her brakes did not turn rotors (right rear is very grooved) dash brake light on. Where and how do I test the ABS? or do you think its the master (but no fluid loss)? OH and how do I tell if it has ABS or anti-locking brakes?

I read in an article that BLEEDING and pad replacement is a regular maintance item? should I try bleeding them?

Thanks Tim

I see that you on answering car questions a lot so when you say it is not loosing fluid I believe you. And that makes me fell like the others except fluid leaking into the brake booster. To find out if the seals in the master are in fact bad remove the cap and have someone push the pedal down slowly. If fluid comes spraying up during the whole pedal movement the master is shot. If it just has a small squirt in the first inch of movement it is not by passing and I'd suspect the system has air trapped in it. You did leave out the details about when it happened like just after the pad replacement or it was okay after that for a while. If it has ABS the two lines coming out of the master will go to the ABS then to each wheel, so it will be a box with two lines in and four lines out. I have no reason to suspect the ABS having anything to do with it.

Yes - sounds like master cylinder:  they can have internal leaks and unable to develop pressure without outward signs of leakage...........but I thought dual breaking system (on all cars since the 1970s) were to prevent that from happening.
