Default Possible Brake problem?

I spent two hours waxing and detailing my 92 vert yesterday. I went to take it for a ride afterwards, and I felt like I was almost unable to stop. I had to apply some weight on the brake pedal. I thought maybe I got some water on the pads? For the next 20 miles - same thing. It's like stopping a tank with no power brakes.

Is there a fuse that aids or supplys electrical power to the brakes?

Any suggestions?

Waxing your car and having brake issues is mutually exclusive.

Yours sounds like a brake power booster issue or a vaccum issue.

In other words, no vacuum pressure to assist the clamping of the brake calipers when you step on the brake pedals, or have vaccum pressure but a broken brake booster.

Do you HEAR the whoosh of air under your feet when you step on the brake pedal?

I do not remember hearing any whoosh sound? I topped off the brake fluid, it was a little low - not much. I'm getting ready to take the car out shortly. Maybe the problem cured itself, probably not though..

Sounds like you knocked the vacuum off the power booster to me. Did the same thing to mine cleaning the engine once. Look to see if the vacuum tube is off. It's located just behind the master cylinder as I'm sure you already know! It won't stop without the vacuum that is 4 sure Al

Your brake fluid's level will gradually go down as the brake pads' thickness decreases. In other words, the more your brakes wear, the more the fluid level goes down. This isn't a bad thing nor does it mean that anything is wrong. You should not add fluid to this container because when you change your brakes, the fluid level will be pushed up and into this container and if you filled it up as the brakes were wearing, you'll have one heck of a mess. Brake fluid does not get used up. It simply gets dirty. You should change it every 2-3 years or when you change your brakes.

If you suddenly lost the ease of stopping your car, it most likely is what the others have suggested. Check under your hood and look for any loose hoses near your booster and/or master.

I was not able to locate the brake booster, While looking around, I noticed a crack on the outside cover of my brakes master cylinder. I started it up and held my finger around the crack. I heard the destictive whoosh sound or air escaping by.

Do you think I could get a way with putty, or 2 part epoxy. Replacing the whole cylinder looks like a big job?




How can I get the picture on this page without just the link?

The master cylinder is attached to the booster.The booster is plastic and really cannot be repaired. Get the FSM and do a search for your problem there are many good write ups on booster R&R's that would take a lot of typing to reproduce. It is a slight PITA.

I want to stress the safety factor here. This is not the component to rig, skimp or short-cut. Spend the money if you don't have the skill to DIY. Brakes are not optional equipment and should be working better than good on these cars.

I named the parts incorrect. The crack is right on top of the booster. If I use sandpaper to rough the surface around the crack, 2 part epoxy seems like it would work well? Maybe, I'm just being cheap and looking for a shortcut?

No you're looking to get youself killed. As previously stated brakes are not one of the parts to "cheap out" on good luck.

If your brakes fail to stop your car...something else will.
