does loosing my brakes while driving mean I would need a new master cylinder on 2000 Toyota Corolla

I take my car in for service on a regular basis and knew that I would soon need rear brake pads. Then I suddenly lost all braking ability and was told I needed remanufactured brake vacuum booster & a new brake master cylinder assy combo at a cost of $515. and labor at $318. along with new rear drum brake shoes $50., rear drum brake hardware fit, $23.; new rear brake wheel cylinders $24 with labor cost of $159; plus stallation/resurface drums/lube all rear drum brake hardware/adjust parking brake (1.5 hrs) complete brake fluid flush & fill @ $130.

If you wold have done the brake fluid flush long ago you wouldn't need a master cylinder. Sounds like you went to a tire store, ie ect. Go to independant repair shop and get a REAL ESTIMATE. Not a bunch of stuff you do not need.

I went to my regular independant mechanic for years and depended upon him to tell me what needed to be done outside of regular maintenance. How often does a brake fluid flush need to be done? And, this estimate was done by an independant repair shop.

There's a manufactured recommended interval. I recommend all my customers at least once every two years. If you do the recommended preventive maintenance you won't have near the problems your having now. The maintenance schedules can be found in Alldata or Mitchell 0D5. It's clear your mechanic doesn't know this. You need to find a more experienced Tech/Shop. As far as the estimate I think your estimate is way off. That is just my opinion. To find out what your preventive maintenance is for your vechicle contact me at I can email you a copy. Good luck
