2004 Lexus RX 330

Brakes problem
2004 Lexus RX 330 V8 All Wheel Drive Automatic 118000 miles

I brought my rx 330 to the dealer because the brake light came on. They said the brake fluid level was low and that fluid was found inside the power brake booster. I was also told to fix the problem the brake master cylinder and power booster assembly would need to be replaced. Estimated cost of repair was over $1000. Does that seem right?

3/26/12: I receive about a month ago a recall notice from Lexus informing me that there is a recall to replace the rubber cups in the master cylinder (mc). I took the car to the dealer and on removing the mc, they found fluid in the booster. The booster will be replaced under the recall.
