When i am braking the jeep pulls to the driver-side.



I replaced the passenger front caliper 5 years ago. May not have properly bled the caliper (i couldnt be inside and outside so i just did my best)



120,000 miles on original brake fluid i figure i did not.



So i bought a pressure bleeder.



I pressurized it to 15 psi and opened the rear passenger side bleeder. The fluid came out very slowly. Roughly 1" linear of fluid (1/4 inch tube) every 30 seconds. Which is slower then i thought it would be.



Then i did the same for the rear drivers side. Same speed.



Then i did the same for the front passanger side. It was much much slower, maybe an inch every 1-2 minutes. Worried it was the caliper i disconnected the hose from the caliper and it was just as slow so i reconnected it and I did the dishes and played games on my phone and only bled out maybe 1oz of fluid.



Then i bled the front drivers side and it was very fast. Very very fast (like the youtube videos)



Test drove and it still pulls to the left.



Any ideas?

I've tried to use a small pressure bleeder in the past for a 1-person operation and I just never had great success at it. I've always defaulted to having someone help me by stepping on the peddle, but I understand your dilemma. That sounds very abnormal to me. All four corners should be sucking fluid out pretty fast, similar to your driver front. You had the cap off the resi when bleeding those 3 corners right? I know that seems like a dumb question, but you just never know.

 

The pressure bleeder is like a garden sprayer that screws onto the brake fluid reservoir.

 

Sorry, "vacuum bleeder" would be what I was referring to -



I see what you're saying about a pressure bleeder. Can't say I've seen anyone use one of those personally. Interesting.

 

If you have an air compressor, they make those that are powered by air.
I have that's specifically made for brakes, and another that's more of a general suction tool (OEM Brand).
The OEM branded one sells an adapter for brake use, but I like my cheap $30 unit for brakes (Plus I don't want to clean the long line of the larger unit).

The one I have looks like this,

The muffler thing on the end broke off, and it now works way better, but I also have a large 2 stage air compressor, so for a smaller unit I would keep that muffler on.
I use a piece of wire or bungee cord to clamp the handle down, then I do the pumping while it sucks.

also "giggity" etc.

 

Pulling to the left makes sense based on what you saw with the fluid flow. The brake lines themselves may have an issue. Since you have one side of teh front working right. If you can push more fluid through them it may clear up but it may ne just that the lines are bad after 11 years.
