I own a 2003 Toyota Camry sportivo four cylinder sedan with only 66,000km. The car has four wheel disc brakes and ABS. About a year ago, I started to notice a shutter so the disks were machined and got new disk pads no problem with that. Few months later I started to notice that there was excessive travel in the brake pedal. . That is, the pedal will travel an excessive distance before there is any braking action. Being an old chap my dad who always maintained my car himself, and diagnosed and repaired most problems, We concluded that the problem was the master cylinder because when stopped at a light, the brake pedal would continue to go down. Incidentally, there has been no loss of brake fluid since I bought the car late 2010 with 36,000km (I am second owner). Recently, I had the master cylinder replaced, and learned that we are not as car-smart as we thought. There is slight to no improvement in the pedal travel problem at lights. Also in the mornings / after leaving my car sit for hrs I have issues with the breaks straight away (excessive travel distance in pedal) and sometimes think the car won't stop down my driveway ;I have tried to correct the problem by pumping the brakes as I back out of my driveway to engage everything but doesn't always help, the breaks slightly work but will then correct itself 100 m down the rd when the breaks actually start to work properly and stop with the lightest touch of the pedal , we have bleed breaks again but can not find a solution. Do you have any idea of the cause my problem?
