Check your brake pads first,as they have a wear warning clip on them.so if you hear a loud screaming noise.Then its quite possible they have worn causing ur warning lights to come on.And i would get anouther quote as that is quite dear for a pump replacement.If it is the pump.good luck pippall!!

Hmm, I'm not sure what a main chip is but, there is a few reasons for this problem.

1. ABS Sensors - there could be something wrong with a sensor and/or the wiring to them
2. The wheel bearing speed sensor in a wheel is bad or intermittent which then tells the computer that wheel is traveling at a faster or slower rate of speed then the rest which in then the computer turns the abs light on.

hows your battery?,for the engine, not the electric motor,Prius,normally dont have any quirky issues with electrics,and behave normally if the car batery is flat,ie...it will behave like any other car if the normal battery is flat or old,check by jumping,(fuse box under hood has terminal for + and put neg(black) on suspension bolt ) 3 each strut top.That should work to see if thats your problem

well, a hard firm pedal, usually indicates a bad brake booster or a vacuum leak to booster or the vacuum check valve, on booster. TO TEST BRAKE BOOSTER; pump brakes several times with engine off to deplete stored vacuum. turn on engine with pushing slightly on pedal. you should feel the pedal fade away a bit and then become firm, but not hard. if you feel nothing at the pedal when engine starts the booster is at fault. good-luck !!

It's a year old. Take it to the dealer immediately and have it repaired under warrantee. Don't wait too long or they might say further damage was caused because you didn't get it looked at immediately.
