Good morning my name is XXXXX XXXXX I will assist you today

 

By the line, do you mean the brake hose??

 

Also, check the lr wheel. if the wheel cylinder is frozen it will build pressure in the front s the rf and lr wheels work together.

Please simplify your answer for me. I did change the brake hose. What I think your saying is that the left rear wheel cylinder and the right front work together. Ok.

That is correct. sometimes a problem in one wheel originates in another wheel when it comes to brakes.

would abs have anything to do with this??Cry

no, the only way it would and this is way out there is that you never changed the fluid in the system, it is black in color and it seized a valve in the abs unit. Extremely rare as it would effect the rear wheel as well.

Sorry to keep asking, but I jacked the van up and the left hand rear wheel spins ok. Dos'nt seem to be locked up.

did you remove the wheel and inspect?? Make sure the wheel cylinder moves when you apply the brakes.

If it does not more then what? Remove and replace it.


 

thats correct. replace it and flush the brake system till you have clean fluid in the lines. thats what causes these failures, the lack of changing the fluid.

replace it, check the other side as well.

Ok I have check my rear brake cylinder. It is working. I bled the brakes . The front right was not froze up. I drove it for 20 minutes and then the right front brake caliper locked up and was smoking real bad. Now Im about to pull my hair out. TO recap what Ive done. I have replaced the left brake caliper and brake pads, I have replaced the right brake caliper twice along with the brake pads. I replaced both rear brakes cylinders. I replaced the master cylinder and the right front brake line. Im ready to replace the car next. !!

Did you bleed the brakes especially the right front to get clean fluid out???

Roy

I bled the rear brakes. Not the front. The fluid was clean.


 

My other concern is a clog in the brake line on the right front. pressure can go to the caliper but cannot return to the master.

Roy

i PUT A NEW BRAKE LINE IN.; and I changed the caliper again. It still locks up. Then after a while it is ok. I dont know. What about the abs unit?

It is possible but you would have a code for a solenoid being stuck closed.

Is there any play in the hub bearing for that side??

Roy
Ask Your Own Car Question
Customer reply replied 4 years ago

no but the rear hub bearings have play and make noise. I ordered two new rear bearings and I will replace them soon.

good but i dont think it will help the right front wheel.

Wish I was there. it would be so much easier than doing this from here.

Roy

Customer reply replied 4 years ago

Well they replaced it with a used one for 50 dollars. But today the Left and right locked up. But I drove it a little and it unlocked. Then It locked again. Now I have about 400 dollars invested and cant get nothing to work? PS I dont have good insurance !!

LOL. sorry to hear that. Did they flush the lines of all debris?? there could be dirt in the lines not allowing any return fluid up to the master.

Roy

Customer reply replied 4 years ago

I assume they did. Any suggestions. !!


 

One other thought. Unbolt the master cylinder and see if the piston on the rear of the cylinder is all the way out to the snap ring. if it does not return all the way it will be in and apply pressure to the wheels.

Just unbolt and move forward without removing the lines.

W. I travel for work and bought a new 2013 Charger SXT with
I travel for work and bought a new 2013 Charger SXT with 8 speed transmission. Late last year October time frame started getting sputter between gear shifts at approx. 175k miles. Had it serviced at dealer and issue progressively got worse. Took into different dealer in different state and found their recommendation to service tranny. First dealer did a 5 quart drain and fill only instead of full service as requested. Also found out that the wrong fluid was used inittially. Once discussed with service manager, he serviced tranny again. Drove approx. 200 miles home and issue got worse. Next day I started on my next business trip and had to return home and park the car. Started having a repeatable sputter at 65mph with cruise set at every 3-5 seconds in addition to a really bad shift sputter (worse than before). Any idea what this may be or how I should proceed with repairs? … read more
