Icon2 1989 CRX SI... Sudden Brake Failure...

Whats up everyone. I have a slight issue that i am looking for some help on.

I was driving today and my brakes just went to the floor. I was driving for about 15 miles before it happened. Lucky me it was right before i was pulling into work.

I pumped the brakes a few times driving around the parking lot and it would get stiff after roughly 2 pumps. Then it would sink right to the floor and lock the brakes. No other symptons happened before this. Brakes were working awesome prior to this issue.

After research I have come to the conclusion it is most likely the M>C but i was just hoping for some input.

I have not looked at the car yet due to being at work just trying to get some suggestions on where to start when i look it over after I get off.


P.S. MC is still full of fluid.

You have a leak somewhere.
Could be a wheel cylinder(drum brakes), caliper(disk), brake line(unusual), or a master cylinder.

If you see no signs of a leak, most likley the M/C leaking at the rear.

Well took it by a local shop from work where a buddy of mine works. He let me put it on the lift really quick to take a look.... well what i found was crazy. Brake line cracked. So who ever said that above is the winner. I ricer fixed it just so i can get home. I cut the brake line and put a screw in it. It held the pressure and got me home safely.

After seeing how rusted my drums were it gave me the green light to do a integra disc brake swap. So if any one has the rears from 91-93... let me know i might be interested. ....

I took a few quick pics as well for lulz later....
