Brake Bleeding question

[bass1775]

I had to replace a front brake line recently. Will I have to bleed all 4 wheels or can I just bleed the fronts?

You "could" just bleed the fronts but why? If your already doing the front, why not bleed all, better yet do a complete brake fluid exchange especially if it's been more then 2 years since the last exchange.

Yes you can just do the front.

I did'nt want to mess with the rear bleeder valves if I did'nt have to. I've broken some before. However I might just take my chances and get a good bleed.

Thanks!

Dont go crazy with penetrating oil but i usually give all my bleeder valves a quick shot before i start doing stuff like that. That way by the time i get to bleeding lines the penetrating oil has done its job. Also for the initial turn of the bleeders use a 5 point socket you will get a better bite on them. Less chance of rounding one off and with a socket you can get a straight solid grab on it so there is less chance of snapping one off.

Bleed all 4 wheels......brakes isn't a system you only do it half way

I also agree with @David Paul on flushing the DOT3 out every 24mos or 24,000 miles

USE A LINE WRENCH, THE PROPER SIZE..... Use the right tool for the job. Spray with penetrating oil and give it time to work. Some times if they are giving you a hard time, you can try tightening them a little first and then loosening. I vote bleed them all. If the master cyl isnt already empty, empty it first and refill with fresh fluid, and bleed until you get new fluid out all 4 corners.

On tough bleeders I will spray them and let it sit. Then I used a 6 pt socket to crack it open.....less chance of bloody knuckles and rounded off bleeder.

If its really tough I spray it, warm it up with a torch, then back it off with a socket. In 28 years of working on brakes I have only had one bleeder break off on me.

Ive had several different line wrenches and honestly unless he has snapon or an equivalent top brand tools stick to a socket. Cheap line wrenches you might as well be using vice grips.
