Hi all,
What a great site, wish my very first post wasnt to ask about a problem.
My 2004 Corolla which I have never had a problem with, now has a problem with the brakes. The brakes initially work fine and bring the car to a halt no problems. But as your waiting at the lights or stop sign, the pedal slowley but surely travels all the way to the floor. The brakes will still hold the car stationary and work fine on the next application,then slowley work its way to the floor again.
I have checked the reservoir and the fluid level was correct. Checked around the master cylinder, slave cylinders and fittings and can't find any external leakes. If it was externally leaking I would notice a drop in fluid reservoir level and have to keep topping it up.
I think there may be an internal leak within the Master cylinder. Possibly past one of the cup seals. Would like to know what other mechanically minded members think. If I can be sure its the master cylinder, I can refit a complete unit or kit as I have done this kind of work before on my old Honda Civic.
Cheers guys, any advice much appreciatted.
Merry Christmas to you all.
Nigel
