If you're POSITIVE you don't have any rusted brake lines, I would first bleed all the brakes to get rid of air in the lines. If not, the master cylinder cap may not be sealed correctly. They are cheap to replace and available at any auto parts store. If you still have the problem, your brake calipers could be going bad, letting air in and possibly fluid out of the piston(s) while moving. Your ABS system might be to blame (if equipped) but highly doubtful. Hope this helps.

How do I tighten my brakes when I press the brake pedal


The only basic thing most (non-technical) people can do is to check the brake fluid level and replenish that, if you still have problems after a few 'pumps' on the brake, there might be a problem on your brake system. (Which is quite a complex hydraulic system.)

You should first have a qualified person check your brake pads, if they are very worn, more brake fluid is required to fill the cylinders.

When that is fixed, they should check the master cylinder and brake linings for any leaks.

Hope this helps.

My brake pedal goes all the way to the floor


Brake pedal goes to the floor? When does it happen. That is the most important piece of information. Most brake systems are power assisted via vacuum from the engine. Your brake booster is what makes the "power assist" work. There are some specific times when you will feel your brake pedal "fade" to the floor and it is normal due to the cycle of the brake components operation.If your brake pedal goes to the floor every time you step on it, stop driving and get to a repair facility! If the pedal is working when driving and the vehicle seems to be working as it always has, then chances are there is no concern. To be on the safe side, have it checked the next time you are in for any other type of service.There is a sensor inside most brake reservoirs that activates the indicator light in your instrument cluster when the level is lower than it should be. As your brake pads wear down, the system requires more fluid so the level at the reservoir drops setting the light. Same thing if there is a leak. The fluid level drops and the light goes on. This brake fluid leak would most likely be combined with a spongy pedal or a pedal fade every time you step on the brakes. A leak would also almost always have a wet area around the leak. Sometimes the leak can be internal to a part of the car you cannot see, so don't count on it.One easy way to check most brake boosters and the brake system for leaks is to turn the vehicle off and pump the brake pedal. Every time you depress the pedal you should feel the pedal "height" come up and the pedal get harder. After a few firm pumps of the pedal, hold it down. Leave pressure on the pedal for 20 seconds or so. Does the pedal move slowly (or quickly) to the floor? If so then there is a leak somewhere in the system. Keeping pressure on the brake pedal, start the vehicle. Does the pedal no drop? It should. That is the power assisted vacuum kicking in as the engine starts to run.The bottom line is that we are talking about your brakes. Your life, your passengers lives and the lives of others on the road around you depends on that system working properly. If you have any doubts, or feel uncomfortable, take it in to have it looked at. Know specifically what it is doing so that you can have your repair facility look at what you are feeling and tell you if

Brake pedel goes to floor & no brakes. I changed rotors & pads 4 mos ago. Has fluid in resevior. Can`t get to pump up.


check the master cylinder. it can go bad without leaking. the fluid bypasses the internal cups causing a fall in the pedal. also if you broke the lines lose to do calipers you might have air in the system bleed it good. if not i suspect the master cylinder

Just changed rear brake pads on 05 mazda 6. now


This is normal and you need to keep pumping the brakes till they reset there self. Once the brake peddle have reset there self and is firm, check the brake fluid level again and add brake fluid if low. After brakes have reset there self, go for a test drive around the block and check the parking brakes. Good luck.

Brake pedal will go all the way to the floor


make sure brake fluid is full. then pump brakes for one minuite check the fluid to see if it went down or stayed full. if it went down then check the system for a leak . if it stays full then you will need a new mastercylender . i dont think you have a vacum problem cause this causes a verry stiff brake pedal not one that goes to the floor

Brakes bad even after replacing pads/rotors


You need to replace the master cylinder. If all else is good and the petal goes to the floor, that's really about all it could be.
