Several possibilities.
One is that you could have drum rear brakes that are really worn down and out of adjustment.
Another is that you could be out of brake fluid and have sucked in air.
Another is that the master cylinder could be leaking.

First check the fluid reservoir.
If the fluid is empty, low or very dark, then you need to fill and bleed first.
Then check for leaks.
Dripage or accumulation behind the rubber dust covers.
Check friction material and replace as needed.
Careful if you filled the reservoir, because retracting disc pistons could cause overflow.

Bleeding is always done with the furthest valve first.
Pump pressure, then quickly open and close valve.
Refill reservoir often to change fluid.

You hit it on the head. that sounds like a hydraulic pressure problem. If you are low on brake fluid it is probably a leak (line, caliper, etc.) and there should be a brake "warning" light of some kind that is on. If 'no' to both of those, it is most likely a bad brake master cylinder. it goes without saying the car is very dangerous to drive...

All you have to do is what i did, remove master cylinder using couple of ring spanners also a 3/8's ratchet with i think a 14 or a 13 mm socket. remove and look inside u will find an adjustment for your master cylinder. it is self explanitory u will laugh and figure it out like i did. this is not a 1st try get it fix. u keep adjusting until happy. No need to thank meC;

When i press the breaks the breaks pedal goes all the way to the floor


you either have a busted break line or your master cylinder needs to be replaced. check around all wheels for fluid leakage , If no fluid seen check to see if the cylinder is full , If mot fill it and pump the breaks and look again for fluid leakage.

I pump the breaks and can build up pressure, but it takes a bit to stop. Very unsafe. What's the next thing I can look for to fix my problem?


You don't give a make, model or year of the car. So a generic answer would be to start looking at the ABS sensors or the BCM unit if the car in fact has ABS.

I have a 94 caprice classic that wil crank but it wont turn on. It just got a new ignition and key for it and it still is doing this problem. it says press key fault and low oil pressure then it shuts off....


You vehicle is equipt with a fail safe switch incase your oil pressure is low it shuts off the fuel pump, More likely your oil pressure switch will need to be replaced,its 2011 relace the oil pressure switch more likely the sensor itself has failed,(oil breaks plastic after awhile,) make sure you have motor oil in the crankcase check the level,

My breaks on my 2000 honda civic are not working well. when u press on the breaks theres not much resistance any more and the car does not stop right away


If you had recent brake service, then they may need to be bled properly. If they are bled properly, then you may need to give vehicle a few miles to adjust and stabilize the pressure between the pedal and the rotors/calipers. The other possibility, if you have NOT changed your brakes, is that you may simply need new brakes.

Good luck!! :)

Stopped at stop sign then sometimes i start moving forward what could be causing this


have your breaks and master cylinder pressure checked. maybe your loosing pressure and the brakes are slipping, if it moves and you let off brake and apply again does it hold the car ? On automatics i Have seen a torque converter malfunction that applies torque to trans which would apply pump pressure to trans wanting to make the car very hard to hold,possibly stalling the car out, Possible but uncommon.

Our kia amanti's breaks build up and stop the car, then when we use a wrench and blead the line under the hood the breaks start working normally again.


do you mean that you pump the brakes to build up pressure in order to stop?

bleeding brakes requires you to bleed them from each wheel starting at the right rear. procede as follows: have someone sit in the drivers seat. have them pump the brakes slowly and forceably to build up pressure. maintain force on the pedal. starting at the right rear, open the bleed screw slowly. the pedal will go to the floor and the fluid will drain. hold the pedal to the floor and tighten the bleed screw. repeat this procedure several times until you are sure there is no air in the line. follow these steps at each wheel- left rear, right front, left front. keep reservoir filled with fluid. fill after each wheel. (note) get a length of rubber hose that fits snuggly over the end of the bleed screw
and drain fluid into a container.

i think you were draining the anti-lock brake system. in which, case follow the steps above for that also.

Toyota lucida under normal breaking the breakes seem ok, if i pump the breaks while slowing down they stop working any ideas


Firstly, why are you pumping the brakes to slow down. If its because the brakes are not efficient, then they need to be checked and repaired. Secondly, it will reduce the braking efficiency to near enough nil, if you are pumping the brakes, doing that, exhausts the vacuum pressure that gives the brakes assistance.

Oil pressure warning lamp flickers when in drive at a stop at idle


2.7 engine I ASSUME??????. A larger inlet for the oil pump is needed. Call the dealer parts dept. about it. This engine had lots of oil sludging and timing chain problems. Fix them before the chain breaks, or its BIG BUCKS to fix. I would recoomend having your mechanic do the oil pump and check the timing chain/ water pump components.
