I pulled up outside our house yesterday and noticed that the brakes had trouble stopping the car and that a previously non-existent vibration had appeared under braking. This was transmitted throught the brake pedal to my foot. The brake system still pumps up when stationary and in reverse for some reason. I have checked all lines and reservoirs for leaks. I have also changed the pads although they still hada fair bit left on them. The disc are fine. The vibration appears to happen through the first half of the brake pedals action if you go through this point then the braking improves,
Has anyone got any suggestions before I resort to taking it to a garage?

Re: Honda concerto brake problem
The vibration is the sign of a warped rotor. If you buy new ones stay away from the ones that are made in China. They rust very quickly and warp very easily. Stick with the ones made in Canada or US. The perception of less braking power could also be a function of the rotors. The car will not stop as well if the pads and rotors are galzed. The surface of the rotors should be a little rough.

the brakes got this device on it called limiter its a notification that it time for new brakes, rotors mite need turns or rotors need replacement, do not wait to long, you begin brake failure, parking brake maybe sticking while you are still driving.
Very hard to give definate answer, intermitant failiures are rare on a hydroulic brake system , brake pedal pressure is created by brake fluid moving to the wheels in a leak free route, for the pedal to drop MUST mean a loss of pressure in this route, your problem could indicate a brake master cylinder or brake servo due to its intermitant nature, close to impossible to diagnose when problem is no actually happening at time of inspection...best of luck
The brake light switch on these trucks was a poor design. Its mounted on the brake pedal. Look under there and bend the bracket that holds the brake light switch slightly and things will start working again. When these were new we used to just grab the brake pedal and pull it toward the drivers seat really hard and let go. This fixed your problem 99% of the time.
Check the ground to the brake light socket. I had a similar problem on a 98 626 and found the ground connector corroded in the socket.(it is on the outside of the socket between the metal insert and plastic housing) Pulled the remnants of the connector out far enough to solder a piece of wire onto it and then soldered it to the metal socket. Lights started functioning normally again. It seems that a bad ground on one socket affects every light in the circuit.
Sounds like you might have a caliper that is stuck and is not fully disengaging. If it is in the rear then you may have a bad rear caliper. Twoo things you can try. One is to crawl under the ca and adjust the tension two nuts on the emergency brake line. If that does not resolve the problem then remove the back tire and try to spin the drum or rotor whichever you may have. If it does not spin then try adjusting the e brake cable more if it still does not respond then you need to do a brake rebuild. Also does it pull while it is dragging? If it is then you will need to rebuild the brakes no matter what.
