Remove the master & clean out the bore & junk on the piston,
then have a helper push the pedal when you open the bleeders

Mostly air still in there,as long as the flex hoses are not collapsed
inside or the caliper pistons rusted & you removed ALL rust from
sliding surfaces & used anti-seize on those areas

If the system is not flushed every 2 years on ALL vehicles,
you can have moisture issues,hopefully not the abs hcu unit

It won't come into play until your doing 16 to 22 mph, depending
on the vehicle & it's strategy

You may have a bubble in the ABS. You can try bleeding there by loosening the lines one at a time, like bleeders. I have read that you might need a special rig to bleed some ABS systems. :-(

SOURCE: 1994 corolla...brake pedal goes to the floor

Assumeing you have no big leaks in the new brake lines witch you would see because there would brake fluid all over the ground I would say you didn;t bench bleed the new master cylinder There is air in this part when you buy it and you need to get it out before it will work Heres how you do it first you need a kit it consests of plugs that you screw into the holes that the brake lines go into but they have fittings for hoses to plug on to them you put the master cylinder into a vice screw the plugs into the holes put the hoses on the fittings and put the other end of the little hoses into the cylinder resivior fill the resiviors with brake fluid then take some kind of a tool i like to use a 6 inch 3/8 ths socket extentoin because not sharp but you could use a screw driver And push the piotion in from the back of the unit repeataly until you see now more air bubbles coming out of the two little hoses that are in the resiviors like ten or so pushes Then reinstall hook up the lines and bleed at wheel cylinders with wheel cylinder bleeding always start at the fertist wheel and work your way back to the closetes wheel Its not as hard as it may sound good luck

Sounds like there is a fault with the vacuum pump not generating enough vacuum for the brake booster assist, or a leaking vacuum hose. Try pinching off all the vacuum hoses to see if the problem goes away. Could also be a leak in the brake vacuum booster itself

After bleeding brakes still have spongy brakes


you still have some air in the lines. go back thru the bleed process again if that doesn't work, get to a power brake bleeder.(amazon about$70) that is a system that puts pressure on top of mc to push fluid thru the system as you open bleed screws. did you know you can adjust brakes by holding down lock button and pumping emergency brake handle. good luck

Check the rear wheel cylinders? Was anything leaking at the master cylinder? Does it have ABS?
Check the front caliper slides are free. Check the front caliper pistons for leaks as well. This is all assuming you bled the brakes(all 4 wheels) properly after all that replacement! You're getting air from somewhere for sure or if it has ABS, the pump may have a problem.

Driver side brake not bleeding properly after bleeding left side and changing rotors, calipers, and pads?


first of all make sure master cylinder is full of brake fluid.then you crank car leave foot off brake pedal. watch abs light on dash it should turn off in 10 seconds if not have car towed to garage or dealer. they have to use a scanner to scan the abs brakes if abs light turn off in 3 seconds. then starting bleeding from master bleed the lower brake line fitting at the proportional valve followed by the upper brake line fitting. keep eye on brake fluid in mastercylinder dont let run dry.next prime the abs hydralic modulator.connect the bleeder hose to the rear bleeder valve on the modulator.place the other end into a container partially filled with cleab brake fluid.make sure the end of the hose is submerged.open the bleeder valve slowly about 1/2 to 3/4 turn have an assistant depress the brake pedal and hold it in the depressed position. when the flow of fluid ceases close the bleeder valve.repeat process until no air bubbles are present in the fluid.then tighten the bleed valve securely. start bleeding brakes. your bleeding sequence is right rear - left front - left rear - right front.WARNING IF ALL FAILS YOUR BRAKES DONT FEEL SOLID AND FEEL VERY SPONGY.DONT DRIVE CAR. HAVE IT TOWED TO DEALERSHIP.THEY WILL HAVE TO PRESSURE BLEED YOUR BRAKE SYSTEM.

Brakes are spongy,light keeps coming on,even after bleeding them


If there are no leaks from wheel cylinders, calipers and lines, likely there is a bypass condition in the master cylinder. If so, replace it.

VR-4 Auto 1996/97 with spongy brake pedal


if you have not fitted brake pads to it [as these can take time to bed in ] and give the pedal a soft and extra travel feeeling you have air in the brake system the simple check to do is look behind all your wheels see if you can see brake fluid sepping down the back plates or any damp patchs which would inply there is a problem if not pick your bonnet up have a look around your master cylinder to see if theres any sign of a leak that was the easy bit if you can,t see anything you will have to take the wheels off to find out what is leaking don,t forget if you change one of the seals or calipers or cylinders on that axle change the other side yates210456
