I own a 1989 Accura Integra. Yesterday I took my car and had my oil changed and nothing was wrong with the car. Last night the brakes started acting up and today the brake pedal goes to the floor when I try and stop. What could have caused this? :confused:

Honda/Acura recommend changing the brake fluid every 24 months. When this is not done, you set yourself up for brake failure. Replacing the brake fluid replenishes the lubricity of the fluid, helping to prevent seal wear, purges moisture and air, and restores anti-corrosion properties. You likely have a caliper, wheel cylinder, or master cylinder that's leaking.

You didn't grasp what I said. The brake fluid needed to be changed every 2 years, since 1989. Having the brakes done (pads and shoes replaced) and the fluid checked 4 months ago is almost irrelevant--by then, the damage had already been done. In fact, if you have your pads and shoes replaced and you have not been regularly changing your brake fluid, it can be the cause of your problem. Thicker pads and shoes force the pistons and seals back over all of the abrasive crud that has formed in the calipers/wheel cylinders. Then, it doesn't take long for seals to fail, brake fluid to leak, and pedal going to the floor. Pretty clear?

What you should have done is have the calipers and wheel cylinders rebuilt, before installing new pads and shoes. If you had been regularly changing your brake fluid, every 2 years like Acura recommends, you wouldn't have this problem.

Not to mention that the fabric lines degrade over time, changing the fluid in them cleans the lines out to allow for more hydrolic action to occur. But, what could be the issue is that your boots on your actuators (calipers) have holes in them. But you would know this by seeing small puddles under your wheels.

Nice thread.
Thanks for the info. I got brake problems couple of days now. My friend recommend to change to EBC brakes. I think I'll be needing a replacement now.
