check the anti lock solinoid to the rear brakes, it has a valve and a resiviour in it, it is in the line to the rear brakes, usually the valve or diaphram goes bad, easiest way to check it is to bypass with a piece of brake line

Try a clean and adjust on the rear shoes, because sometimes when they aren't properly adjusted they won't seem to work properly. Also there is a common "squishy" petal feeling after brake work on most all larger GM's around that year, wich I have run into several times. Try test driving it, and put a couple miles on it, That usualy helps.
Good luck!

SOURCE: Power steering pump on a 1978 Chevy half ton

First, remove the ps belt by loosing the adjustment bolts, then remove the hoses from behind it, then unbolt the bracket from the engine that the pump sits in. I believe that there are three bolts that do this. One off of the exhaust manifold, one on top and one underneath. Once you have gotten pump off of the motor you need to remove the pulley from the pump. KD tools make a great tool for this, part # KD 2897, about 60 bucks at napa. Follow the directions with the tool to remove the pulley and to replace it on the new one. New pumps don't come with the pulley and can be bought with the resevior. The pulley has to come off to get the pump out of the mounting bracket.

SOURCE: brake bleeding

if you didn't bleed the lines after putting the master in. then there is a good chance there is air in the lines now. may go through a quart of brake fluid before all the air is out. remember to start at r-rear/ l-rear/ r-front/ l-front last.will take some time. don't forget to adjust the rear brake while your there to help with the pedal

SOURCE: 1978 Chevy 1/2 ton Truck - fuel is not getting to

On the front of the carburetor where the fuel line comes in is the fuel filter.Did you change that?Take off that line and slip the end into a container,coffee can size.Have a friend turn over the motor,watch for fuel.If you get fuel your needle and seat have seized in the closed position.No fuel check the rubber lines that hook to the fuel pump.You replaced the pump,it's only $2 worth of rubber hoses.If they don't seal the pump can't pull the fuel,it's cheap insurance.

1978. Can a rear cylinder cause the brake light to pop on and stay on?

The light would only come on if the parking brake is on or if the master cylinder is low on fluid.
You may have a problem with the master cylinder or equalizer valve.
The line could be clogged, you could use a suction gun to try to pull fluid thru the line.

Changed out the master cylinder on my 1978 chevy scottsdale. filled it with brake fluid. now I have no brake pressure at all. what did i do wrong?

Gotta bleed it. It's been written up a thousand times, google "how bleed brakes" and you're set for a little studying.

If you have trouble freeing the bleeder fittings, try: a 3/8" impact, set it very low and let it tap away. Sometimes they'll turn after a couple of minutes of steady application of the impact. If you don't have an impact and you fear breaking the fitting, grab it with a little pair of Vise-grips and tap the vise-grip handle in the proper direction. Just keep tapping, it can take a few minutes. Clamp the pliers on tightly, don't let them slip- they'll really eat that little bleeder quick if you let them slip.

Don't mess around with junk locking pliers from the exotic Orient, they are pretty much without value. The only Vise-grips worth owning is the originals, and the 5" version is incredibly useful for things like breaking the little brake bleeder fittings loose.

Can you easily convert manual brakes to power brakes on 1978 Chevy c10?

U will need a power booster, a power brake master cylinder and a proportioning valve, u will need a good tubing bender to make up a few brake lines to the proportioing valve from the master cylinder. on a scale of 1-10 this is a 7, 10 is mot difficult.

I have a 1978 trans am with a 403 and have no brakes. does the booster use manifold or ported vacuum?

You should have brakes, but a really hard pedal to push, if your booster has no vacuum. If your pedal goes to the floor, you need to fix that problem first.
Check all wheel cylinders for leakage, and check the level of brake fluid in the master cylinder.
Your brake booster has a large vacuum hose that hooks directly to the back of the manifold/ carb base assy.
