Just bought Ek coupe, I notice there are no brake pressure at all. My brake going all the way to the floor and very very little braking at the end of pedal travel. The pedal does goes up to normal, it just no brake at all. Pedal feel like it leaking air pressure right out. I didn't see any leaks and fluid still full after alot of braking.

I did change a different master cylinder, still still no pressure.
Change rear pad, still same.
There no leaks in line, fluid still full.
Only thing can think of is busted wheel cylinder, and caliper??

Anyone had any idea about no pressure.

Thank for replies.

nonsense

I would have voted for the master cyl being bad, but since you changed that I'm not sure. Did you replace it with a new or rebuilt MC, or was it another used one? Could it be a bad one you replaced?

Usually when a wheel cyl or caliper go bad they will lock up or leak. Since you're not seeing any leaks and not losing any fluid it's probably not that.

Did you make sure that you bled the brakes really well? Did you bench bleed the new MC? Also check the brake booster and adjust the pushrod if needed.

Do the brakes get firm after pumping them or do they always just sink to the floor with no pressure? Try pumping the brakes with the engine running, and again with it off. Let us know what happens

I replaced with a use one. It said to be in working condition, maybe not. I try pumping with engine on; it just sink to the floor with no pressure at all. With engine off, pedal get little hard, but no brake at all. I dont think alittle air bubble in the system cause no brake at all, could it?.. I think your right about MC, it could be a bad one again. Should I go to honda buy a new one or keep testing??

Thanks
