Help!!!

My jeep is acting wierd. I didn't notice it until I got off free way. It started pulling to right hard. I pulled into parking lot then I heard a squeak. I put clutch in and I came to stop on a down hill. Could it be my brakes? Please respond!!!!!

I think it's my left front brake it's almost like it's locked up. I'm guessing this because of the heat it's radiating

it was my caliper. it was siezed. got a new one and put it back on, but it seems like it takes alot more pedal to start braking.

I'd bleed from the farthest one opposite the caliper you replaced. Clutch should be ok if you never messed with it.

Alright thanks. I think I'll bleed them all to be sure I have no air in system.

And rotor. I am currently trying to bleed my brakes but all I am getting is air in passenger rear. My buddy's pumped it atleast 100 times and nothing. Anyone have any suggestions.

If the medal is soft and nothing's pumping out at all, it's your master cylinder.

did you keep the oil full in your master cylinder while pumping and bleading. and did you close the bleared while pumping the pedal up.

Yes. And I had someone pump like crazy, crack the bleeder screw and close it. Get a shot of air out, repeat until only fluid comes out when you crack if open.

Okay so it was leaking from the passenger rear . The nipple was blessing so I took it out and saw metal shavings. Put back in by hand and it still leaked . The nipple thread looked fine but I am concerned about the part where the nipple screws into. Is the part of the piston for the rear drum brakes?? Could I replace that or should I start looking for new axle. Please respond quickly as this is my dd.

You can replace it, I believe it's only like $12 at most and is called a rear wheel cylinder

I wouldn't normally recommend Teflon tape but might be worth a shot in your case. Put some on the bleeder screw and crank it down.

You'll probably need a 3/8" flare nut wrench for the line fitting and they usually come with new bleeder screws

also, according to the repair manual the proper sequence for bleeding brakes is driver front, then passenger front, then passenger rear, then driver rear.

Alright thank you so much. I'm going to fix it after school tomorrow. I really need to do a safety tune up. This is second time brakes acted up.

Harbor Freight sells a bleeder pump ...cheap.Thats what I used on mine.On the front calipers the bleeder screw should be on top.there is a l.and r. caliper and if installed on the wrong side the bleeder screw will be on the lower part of the caliper and you'll never be able to bleed the brakes...russ

So what impact does the bleeder screw on the piston have? It is a pressure system if the pedal is mushy or soft there is air.

You said your buddy pumped the pedal really fast that is wrong you are just spreading the air around in the system get a helper he should slowly push the pedal to the floor as you crack the bleeder screw once pedal hits floor close bleeder firmly then he lets the pedal come back to the top and gets ready to push to floor again as you crack bleeder this is not a fast process slow and steady. Also make sure the reservoir never gets empty if it did then you have to bench bleed the master cylinder.

You can google bench bleeding master cylinder
Also look for leaks at the power booster and the master cylinder that can cause air leaks.

When all is said and done pedal should be firm if not you still have air keep pushing fluid thru till you pump at least five times on one caliper with no air. Why five because it sounds like you have a lot if air.

I was filling the wrong reservoir I guess. I thought it was the small one but I popped open the thing infront of brake booster. I filled that up because it was sucking air in. it's all good now.

Glad you got it fixed the thing in front of the brake booster is the master cylinder in case you cared what it is called

When you bleed your brakes on the jeep do you have to fill that instead I the other reservoir ?

The other small res is your clutch master cylinder if that's what you're filling. Yes. The large metal one needs to always be filled when bleeding.

Just to make sure I understand you perfectly there are two reservoirs a small one and a larger one. The small one is for rear brakes the larger one is front brakes. On the older jeeps because they typically had disc brakes front and drums in rear they made two separate reservoirs. Rear drums take less pressure and less fluid to engage a lot of owners upgrade rears to disc the combo proportioning valve is not really designed for that but there are several ways to deal with that.

I am avoiding the topic because it always blows up into a multi post discussion about brake bias and other things.

Newer TJ's have disc brakes all around I think some older Rubicon's also had 4w disc brakes.

Regardless once you upgrade rears you need to tweak the system so to speak to insure optimum brake performance.

Now if you are not talking about the small reservoir in the front part of the Master Cylinder, but instead are talking about a small plastic reservoir close to the firewall that is the clutch master cylinder.

I am sure this is way more info than you wanted!
