That is your clutch master cylinder leaking. it will leak inside and cause a big mess. They cost between 47.00 and 75.00 depending on the manufacturer and where you buy it from.  PBR's (an after market manufacturer) part number is JG83-41-400.

You have a leak in the master cylinder. If brake fluid is leaking into the vehicle I would say I have not heard of this problem before but anything is possible anyway the likely problem is the master cylinder is worn and leaking fluid and air - that's why you have to puimp the brakes. It really isn't that expensive if you provide the parts once it is diagnosed - you really should get it repaired right away though because they can go out completely without warning. Hope this helps.

No brakes, see fluid leaked out, can't see from where, press while engine running and it won't build up pressure, turn engine off, and it will build up pressure

Air in system can try to bleed brakes but leak needs to be found can wash fluid off with water and let dry add fluid and pump brakes see where fluid is dripping

Why do my brakes pump up after bleeding and still go to the floor when i start the truck?


If the brakes pump up after you start your engine, it means your brakes are good and there are no bleeds.

They pump up as the car builds pressure inside the brake fluid circuit.

If the pedal loses pressure and hits the floor while the engine is on, this means that you may have brake fluid leaks and your brakes won t hold much longer (needs immediate fix).

I have a 93 Mazda mx6 Ls... Everytime I step hard

When my MX6 was doing this it turned out to be an hydraulic leak from the clutch master cylinder, which runs on the same fluid reservoir as the brakes. Clutch master cylinder replaced and all good again!

Constantly on dash brake warning light 2000 chevy venture. the emergency brake warning light on my 2000 chevy venture is constantly on. the rear brakes aren't sticking and the switch seems simple how...

Please also note that the low fluid level sensor in your brake master cylinder will also make this light come on. If the brake fluid is low in the master cylinder, you need to find out WHY! There is either an hydraulic leak in the system or the disc brake pads are worn VERY thin. Then again, the low fluid level sensor could be faulty.

There is also a difference in brake systems available in your vehicle. If you do not have a fluid level switch in you master cylinder, there will be a pressure differential switch mounted between the fluid lines just below the antilock brake module. If this switch is causing the brake light to come on, it is usually because of a fluid leak somewhere in the system. If the hydraulic pressure on one dide of the switch or the other drops for some reason, it will cause the piston in the switch to shift to the side and turn the switch on. Again, you vehicle may be equipped with one or the other - you simply have to look.

To find out if it is the low fluid level switch, the pressure differential switch` or the parking brake switch, just unplug each of the switches to see if the light goes out.

If it actually is the parking brake switch, it is usually because the parking brake lever assembly is malfunctioning or you may have a stuck forward cable that is not allowing the pedal to return to the full UP position. Parking brake lever/pedal assembly failures are pretty common. I have changed quite a few of them.

Our rear brakes were bad so ordered new ones. while waiting for them to make their way to the auto parts store the brakes stopped working. i would push them down to the floor and barely stop. and the back...

make sure that there is fluid in the master cyl. and then you need to bleed the brakes, always bleed from the farthest wheel from the master cyl. first, to the closest wheel last. there is air in the system, you can test this by pumping the brakes and they will get harder as you pump.

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 travels all the way to the floor.pressure builds when you pump the pedal.resivoir full of fluid and no lines are leaking.

Fluid may be bypassing seals inside the master cylinder giving you a low pedal on first application and building up as it continues to be pumped. If drum brakes make sure rear brakes a well adjusted

Brake fluid leaking

It looks a faulty brake pump, to check it- have some one else with you to watch the pump fluid while you are pumping the brake pedal, if there is an air bubble come up the fluid then you should change the brake pump or kit.
