Customer Question

I need help with bleeding my breaks on my 2005 Cadillac STS, I don't have any sophisticated equipment so far I got just a very little petal. I had to change some of the front break lines so I must bleed them.

Hello and welcome!

My name isCustomerand I can assist you with your question.

Bleeding the brakes should not be a complicated task. Just open the bleeders on the front brake lines, remove the cap from the master cylinder and let the fluid drip. This is called gravity bleeding. Do this until you have a small puddle of fluid under each caliper. Then close the bleeders and bleed one side at a time.

Expert:  Amedee replied 10 months ago.

Bleed each side until there is no more air that comes out. Also, be sure that the master cylinder reserviour is full before bleeding the brakes.

When each wheel is bleed do I then start engine and bleed again by pumping up petal and open valve allowing petal to go to floor and shutting off valve?
Expert:  Amedee replied 10 months ago.

You would leave the engine off when bleeding the brakes. Bleed both sides and then you can start the engine to see if the brake pedal is nice and firm.

Ok I understand, we tried bleeding each wheel by pumping up and open valve to get air out and it didn't work, so your saying gravity bleeding is better. I will try.
Expert:  Amedee replied 10 months ago.

Your welcome.

Try gravity bleeding them first. I would do this for about 20 minutes and then try bleeding them with the brake pedal. That should do the trick.
