Question about 1995 Chevrolet Lumina

1 Answer

95 Lumina rear brakes/low pedal.

So, I`ve isolated my low pedal issue to the rear drum brakes. I pinched off the 2 rear flex lines and immediately the pedal was at the correct height. I released the driverside rear hose first and there was a slight drop in the pedal, then the passengerside...back to very low pedal. Bled the rear brakes again. No change. The rear drums are new as are the shoes. Could the wheel cylinder (s) be bad???

    I was thinking the same thing. I`m finding with both my Chevs that OEM parts seem to be the best choice. I`ts possible that the wheel cylinders were replaced with aftermarket ones before I bought the car, and are either wrong or not manufactured correctly.



    Thanks once again. I`ll report back when I`m done.

    Well, you were right! I replaced both rear wheel cylinders and like magic, I have a normal brake pedal height! Thanks once again for all your help!

IT IS POSSIBLE THE WHEEL CYLINDERS are wrong and need too much fluid to push brakes out. or rear shoes are not adjusted correct. this could be from drums too big(unlikely since new) shoes are not fitting to drum correct.You can take shoes off and set them in drum the whole shoe should contact drum sometimes just the ends contact. If this is case sand off ends of lining to make it fit .
If wheel cylinders are bad they would leak. might try a different brand of cylinders.

What is the part called that the brake lines hook into?


Hi,
Under the hood is the Master Cylinder. It contains brake fluid, which when you depress the brake pedal, acts as hydraulic fluid to flow through high pressure tubing called brake lines, from the Master Cylinder to the Wheel Cylinder (drum brakes) or Brake Piston Caliper (disc brakes). As you depress the pedal further hydraulic pressure expands the wheel cylinder which presses outward, 2 brake shoes inside a metal "drum" (drum brakes) or clamp the brake piston calipers together squeezing a disc-like rotor (disc brakes) thus stopping the vehicle.

Brake pedal was low installed new shoes on rear tried to bleed them feels like i only have right front brakes and pedal is still low are they a way 2 adjust them with out removing the drums ?


Yes, you can adjust them by removing the small oval plug on the back of the back plate on the brake assembly. However you need a brake adjusting tool, you can use a screwdriver in a pinch if the angle is right. It sounds like there was nothing wrong with the brakelines or fluid so there shouldn't have been any reason to bleed the lines. It sounds like there might be air in the brake lines. You might want to make sure they are bled properly, have someone help you by pumping the pedal and holding it while you loosen the bleeder, when the pedal is all the way down make sure it is held down till the bleeder is retighted. repeat this till you get a steady stream without any air bubbles. Never let the pedal move up while the bleeder is loose, this will **** air into the system. Make sure to inspect all of the brake lines for leaks. Don't overtighten the brakes, this will cause the shoes to overheat and crack. Don't short this fix, if you are unsure find someone who has experience to help.

How do you adjust the brake peddle for more peddle


Is the problem your brake pedal is to low There is an adjustment for the brake light switch at the top of the pedal that could affect pedal hight slightly But if down a 1/2 inch or so i would suspect some kind of a problem with the brake system it self how well do the brakes stop the vehicleand have you noticed more of a drop in the pedal over time?

I have a brake line leaking from the back but I need to pinch it off so I can drive it to the garage for repairs , what line do I pinch off from the master cylinder so I just have front brakes.


Tricky and risky ,and if garage is not to far away, use the parking brake and brake pedal at low speeds to stop. Taking out of gear at stops at a light or crossing/stop sign. Otherwise, cap and plug the main line at rear axle brake tee spliter from front.

Brake pedal goes to the floor only when engine is running. Pedal is perfect with engine off.


your power brake booster is blown out
the seal has a leak in it
run the truck for 3 minutes and shut it off. with the windows up listen carefully while you gently apply the brakes
listen for a hissing sound of air leaking.
the sound of these leaking is a very soft sound

Poor breaks


When you open the breaking system you allow air to enter the break lines and that will cause squishy or weak breaks. You have too "bleed" the air out of the lines now. The way to do this is to have someone help you with this process. They will need to pump the break pedal until the break pedal is stiff and hold pressure on the pedal while you open the valve on the caliper or wheel cylinder(disc or drum) until you have a steady stream of fluid with no air. To ensure you get all the air out you need to start from the passenger rear tire,then driver rear, pass. front, driver front. Make sure you slip one end of a hose over the bleeder valve and the other end in a container so that you don't allow the break fluid to contaminate the new brakes,

Low brake pedal


You may have a bad brake Booster and it could have brake fluid in it.
Also you may want to try a complete brake fluid flush.
