***SCROLL DOWN TO POST #34 FOR DIY INSTRUCTIONS***

hi all, i dont own a honda but drive a toyota celica year 2000. thought i would sign up to give thanks to Billman which iv read on here advises with brake bleeding issue and long pedal travel to wedge the brake pedal overnight. so i thought i would give it a try since changing my calipers and hoses ended up with a pedal to the floor before any brake affect was felt.
after wedging the brake pedal overnight the pedal travel was halved. its considerably better now and needs about 1cm travel and i can feel the brakes bite.
i dont know how or why this method works but its worked so well for me so i thought i would sign up and say thanks.

celica is on the left.

This method was taught to me by an 80yr old gentleman at the time, over 25 years ago. He was the owner of a major truck and machine company out here.

I HAVE ADDED the DIY method down at post #34, scroll down.

Why and how does this method work?

Car Analogy

There is a huge amount of psi in a hydraulic brake system when you press the pedal hard. All that pressure in the fluid over time more forcefully incents the air bubbles to move their way up to the mc. Its kinda like it squeezes the air up out of the system.

Then when you finally release the pedal, the air can escape into resevoir.

Its a trick I've been using for a really long time as well. It works for clutch pedal too, just not as well, since the psi is limited by how much the pressure plate pushes back against the hydraulics.

Billman250

In short, it allows large air bubbles to break into tiny air bubbles, and make their way up to the resovior where the exit the system.

when cars are new from factory what sort of method do they use to fill the brake fluid? do they use 2 man method on every car?

using my crystal ball, i see the factory using a pressurized vacuum system to fill the brake fluid. i most definitely highly doubt they use a 2 man method at the factory - talk about a bottleneck in the assembly line

you know, i've always wondered this.
