Recently had my car to garage to have front brakes done. Mech. found out that only left half was getting fluid pumped in. Said I would need new master cylinder. He blew out the m.c. lines and nothing was clogged or blocked. Soooo.. I put on new m.c. and its still doing the same thing. What do I check from here???? Thanks

Re: Help! Brake fluid only goes thru 1/2 the car...
The problem could be in 2 areas. One, it could be that the caliper could be hanging up or is "froze" up not allowing the fluid to apply pads to rotor. If you just had a brake job...did the mechanic replace the pads on the side that wasn't working?....if it wasn't working then those pads should have looked brand new. Second, the other possible issue could be a kinked brake line caused by a rock or something similar that could have come into contact under the car. My suspicion would be the caliper, only because auto makers tend to put brake lines in areas as to not get them damaged from every day driving. See if it would be possible to get a hold of another caliper from junk yard or something and have it installed to see if that fixes the problem.

check the brake booster a lot of times they will leak on the inside of the firewall and run down under the carpet inseide look under the dash where the brake pedal rod goes thru the fire wall and see if there is and brake fluid coming thru
to bleed brakes by myself i use a bottle of brake fluid and get a hose the size of the bleeder on the brakes and put the hose over it and put the other end in the brake fluid open the bleader a little and pump the brakes air goes out and it will pull the fluid back in
From the symptom you have stated, there is a problem with brake system. You have not mentioned whether you have any braking effect on the vehicle when the brake pedal goes to floor. Anyway, you may check the following:
1. Check brake fluid level in the brake fluid reservoir. If the level is less, then you have to go to a garage as just filling up the fluid will not help and the brake hydraulic system needs bleeding.
2. Get the brake adjustment of all the wheels checked by an experienced garage mechanic.
3. Get the Brake Master and Wheel cylinders checked by an experienced garage mechanic.
4. The brake liners might be worn out. Get the same checked by an experienced garage mechanic.
5. Brake pipes which convey brake fluid from Master cylinder to the wheels might be leaking. Get the same checked by an experienced garage mechanic.
Whatever may be the cause of the symptom, do not use your vehicle till you get the problem solved as you are accedent prone without the brake system proper functioning.
1. Put your car on a level spot for safety and start your car Sienna. 2. For left front rotor, turn your steering wheel to the left all the way and stop the engine. DO NOT put emergency brake on! Put stopping blocks on the passenger front front, rear right and rwear left for safety. 3. Half loosen all front left tire nuts and jack up the left front then loosen all nuts and take the wheel off. 4. Use a 3" G-clamp from Lowes, Home Depot or any store near you, press against brake cylinder so that brake fluid flows back to its reservoir 4. Remove one bolt on the caliper and the other bolt loosen and lift the caliper with the other bolt on and rest on a block. Do not take the rubber hose off nor attend to loosen any brake fluid pipes and nuts. 5. Remove brake pads and remove the nuts on the rotor, done. If you need further assitance please let me know and if this assisted you please feel free to rate the solution accordingly. Thanks, Midwest-tek
Sounds like you might have air in the brake system. You will need to bleed the brakes to remove air. Start with the passenger back wheel. use a small hose and submerge the end in a glass bottle filled 1/3 full of brake fluid. The other end goes on the nipple of the brake bleeder. Have someone pump the brakes and then hold the pedal down then loosen the bleeder. then tighten the bleeder. you should see bubbles in the brake fluid. Keep repeating this procedure until you see no bubbles. You might have to put as much as 1 quart of brake fluid thru each wheel to remove air. Then you do the driver side rear followed bypassenger side front and finally driver side front
