2000 ZX3 - Sudden Loss of Brake Pedal

Hi All,

I sold my SVT last year and bought a Mustang. Mustang ended up with 400whp and I picked up a ZX3 as a daily last week.

I've been driving it the past few days, and this morning when I got into the car I noticed that it suddenly had no brake feel.

The brakes still work, but the pedal shoots to the floor. Hopped out of the car and checked the fluid, didn't see any in the reservoir at all.

I filled up the reservoir and tried again (i know i need to bleed them, but i was late for work).

Anyone else have this issue, I checked under the car and couldn't find any leaks.

When i get home tonight I'm going to try and bleed them, but my concern is that bleeding them implies air got into a sealed system somehow.

I don't know anything about this car so any info would be appreciated.

Cheers,
Tom

Sorry for being unclear. I purchased the car last week, and drove it for 4 days. experiencing no problems with the brakes.

The issue started this morning, when i started the car. Last night I had brakes, this morning I don't.

Fluid is not leaking anywhere I can see.

Im not to familiar with this model, but have you checked the pads and/or shoe thickness? You may have bought a car with thin pads/shoes causing fluid to be low, who ever you bought it from may have never added fluid from a previous leak, fluid change, ect.

A few questions thou, is this a manual trans with shared reservoir for the brake system? And did your red brake warning like come on, like if you had parking brake set?

Thanks for the response. Auto, so no sharing fluid for the clutch.

No warning lights, I will check the pads as soon as im home today.

I suggest checking your reservoir to see if it has a connector on it for a low fluid sensor, if it does your sensor may be messing up, or stuck due to old fluid that was never changed. It wont cause your problem but I would do some digging to find out why it didn't come one to keep your self safe.

Ironically it does have the sensor, but it appears not to work, as the fluid was so low but no lights came on lol

The float in the reservoir may be stuck in the high position due to old fluid gunk, you might me able to push it down with a small metal rod or your finger. Try pushing it down while someone is in your car to see if light comes on. I think you have to replace the whole reservoir the fix the float if this doesn't work. I would make sure that the float is the problem before replacing it.

Fill up the fluid. Pump the brakes. make sure that the cap is put on correctly. Then hold them down. Does the petal slowly go down?

At first thought, Master Cylinder or, wheel cylinder leak.

Won't be worn brake parts alone. All masters are calculated to hold enough fluid to cover the entire range of use until brake pads/shoes are dead, the level will be lower but not running out at all. If run out to expose air then leak somewhere.............
