Why are the brakes soft on my Chevy Silverado?
Air trapped in the lines, calipers or wheel cylinders will make the pedal feel soft and spongy. Air is compressible, so when the brakes are applied any air bubbles in the system must first be compressed before the hydraulic fluid will transmit pressure to apply the brakes.
What to do with a Chevy disc big brake conversion?
Next Josh removed the differential cover, drained the gear fluid and cleaned the axle with brake cleaner. Next he unbolted the C-clips and removed the axle shafts. With the new brackets installed on the rear axle, the original axle shafts can be slid back in and the C-clips can be reinstalled.
What kind of brakes does a Chevy Silverado have?
The modulator assembly has fluid chambers for all four brakes, two isolation solenoid valves, four check balls, a motor pack containing three bidirectional direct current motors with electromagnetic brakes (EMBs) and/or expansion spring brakes (ESBs), three ball screw assemblies, four pistons, a gear drive set and gear cover.
What kind of brake does a GM FWD vehicle use?
A prime example of this are GM FWD vehicles that are equipped with duo-servo rear drum brakes. Most FWD vehicles use a non-servo rear drum brake because of the braking balance of a FWD vehicle. These GM vehicles are “over-braked” in the rear which makes them very sensitive to rear brake problems.

What’s the difference between disc and drum brake lines?
Then there are situations like a rear axle with disc brakes could be fed with a single 1/4″ line and branch out into a different 3/16″ line for each side. Some folks tell you as a rule of thumb that 3/16″ is for disc and 1/4″ is for drums… That’s misleading at best.
Why does my brake caliper keep sticking out?
They are pushing the brake pads against the brake disc to make the car reduce the speed. The brake caliper pistons have a rubber boot around them to prevent dust and other particles from coming into the brake system. It is quite common that this boot gets damaged, and water and other dust will come into the piston.
What happens when the brake pedal goes to the floor?
Brake Lines, Brake Calipers Check: The first thought that comes to anyone’s mind when the brake pedal goes to the floor when engine running, is that there is a leakage in any of the brake lines outflows the pressure in the brake system. The first thing you require is to check the brake fluid level. If it is full capacity, then there is no leak.
Why are rear brakes not equal to front brakes?
Equal brake force cannot be applied to all of the wheels on the car at the same time because the rear wheels will lock up. Vehicles with drum brakes in the rear have much lower pressure for the drum brakes than the front disc brakes. This is why the proportioning valve only lets a particular amount of pressure through to the rear brakes.
What causes a noise when you brake on a Chevy?
Brake Chatter: Warped or improperly finished rotors will cause this noise. Brakes that Grab: If there is oil, brake fluid or grease on the pads, they will slip and then grab hold. You may feel your Chevy jerk when you brake. Check your pads for any type of contamination.
Why does the proportioning valve only work on rear brakes?
Vehicles with drum brakes in the rear have much lower pressure for the drum brakes than the front disc brakes. This is why the proportioning valve only lets a particular amount of pressure through to the rear brakes. If you suspect there is an issue with your proportioning valve, check for the following symptom:

What causes a soft brake pedal on a Chevy?
Soft or Spongy Brake Pedal: Too much air in the system due to improper bleeding is usually the cause of this problem. However, it can also be due to fluid loss or a low fluid level. Bleed the brake lines as recommended by Chevy to fix this. You could also have a ballooning brake hose when the brakes are applied.
What does it mean when your front brake is not working?
Brake Pull: Uneven braking means that you have one front brake on your Chevy that is not operating properly. Your brakes pull to the good side. This can be due to oil, grease or fluid on a pad, a caliper that is stuck, brake line blockage, or wheel bearings that are loose.
What causes brake fluid to go down in a Chevy?
Even with proper maintenance, you may find yourself with an unexpected brake problem — here are some of the most common examples. Low Brake Fluid: Your Chevy may develop a leak in the system that will result in the fluid level going down.
