New Brake Line=Back brake pulsating
 

Replace my back brake line when I went up a couple more inches. Bled the brakes and broke a bleeder on back passenger. All the others bled fine except back passenger. It was making a real bad pulsating feeling coming from that back passenger wheel so I replaced the wheel cylinder so I could bleed it correctly. After replaced wheel cylinder and bleeding Im still getting a pretty good pulsating feeling in the brake pedel and sounds like its coming from the back passenger.

Is my drum out of centerfrom doing a little driving with the broken wheel cylinder or could that be caused from air still in the brake line?:dunno:

Thanks in advance.

How are your drive shaft angles? If everything appears okay with rear drum assembly then I wonder if the lift height change didn't throw off the rear driveshaft geometry enough to cause vibes?

Drive line angle isnt terrible. I shimmed it when it went up. This vibe is only from hitting the brakes. The driveline vibe is a different deal.

This vibe comes when the brakes are applied and the brake pedal pulsates. the vibes from the ds come at acceleration.

I would look at the assembly of the brake parts. I have seen parts brake inside of the drum before. I had one of my automatic adjuster cables brake inside of the drum wile i was driving and pretty much render that drum useless till I rebuilt both drums. It is possible that the drum its self could be out of round. try swapping the drum from one side to the other and see if it follows. It also cant hurt to re-bleed the whole system back to front.

Yeah drum might be out of round, the pads might be falling apart, etc. Is the ABS going off? Could help to clean off the area around the ABS sensor if you have it.

No abs here. . .

In pedal usually is a front issue. Rear usually in more of seat of pants feeling. Unless drums are extremely egg.

Definately the back. Its almost like it catches then released really quick over and over again. Could be a crapped out drum
