no you dont have to---BUT its adviseable
from the furthest caliper from the master cylinder. Start with that one and move closer.
Defective master cylinder? Frozen caliper? Parking brake cable frozen?
You will need to bleed the brakes, starting from the caliper furthese from the master cylinder then moving closer.
That depends on where it's leaking out; if it's at the master cylinder, you have a bad master cylinder, if it's at the wheel cylinder you have a bad wheel cylinder if it's at a caliper... well, you get the idea. If you know how to repair a master cylinder, wheel cylinder or caliper, you can often get by with a little savings but it's usually best to just trot down to your local auto parts retailer and get a new or rebuilt one.
Yes, changing the master cylinder can affect the way you bleed the brakes. When a new master cylinder is installed, it may require a different bleeding procedure due to potential air trapped within the unit itself. It's often recommended to bleed the master cylinder before connecting it to the brake lines to ensure efficient brake fluid flow and eliminate air. After that, you can proceed to bleed the brakes at each wheel as usual.
Check your owner's manual, but newer cars can also illuminate the brake light if the fluid in the master brake cylinder is too low. This may have happened if the brakes were bled but not filled, or if the caliper was pushed back in, but fluid was lost in overflow, etc.
If you didn't bench bleed the master you need to do that before you install the master.
This could be caused from the closing off of the flex line or a bad caliper or a bad master cylinder
A rotted brake line, a leaky front caliper, a leaky rear wheel cylinder, a leaky master cylinder,
bad master cylinder calipers rubber caliper hose and if you have raer drum brakes and the rears are locking the brake shoe are wet from the wheel cyls and you are in grave danger
The ECU for the ABS brakes is attached to the Master cylinder for the brakes.
