Hi, My name is ***** ***** for the delay.

I will do my best to assist you

did you replace the rotors?

does it have drum rear brakes?

Customer: replied 1 year ago.
Replaced master cylinder, rotors, calipers, pads, front wheel bearings, wheel cylinders, brake shoes, and drums. New brake fluid and good bleed.
Customer: replied 1 year ago.
rear drum brakes.
Expert:  tims auto repair replied 1 year ago.

and,it only vibrates when applying the bakes?

do you feel the vibration in the steering wheel?

Customer: replied 1 year ago.
Only when applying brakes. Whole truck shudders, but do not show up more in the steering wheel than throughout truck. No pulling and vibration stays relatively constant regardless of speed. Too fast for bad rotors. I have rear wheel anti lock brakes. Sensor on differential reads 1.4 Kohms at frame connector. No ABS light.

does the rear brakes chatter or make any sound?

Customer: replied 1 year ago.
No chatter or sound that I can hear. Brake pedal feels good. Front end is tight.

No pulse in pedal. Pedal feels good.

ok,,it is doing the same after the work as it did before?explain

Customer: replied 1 year ago.
This has been making me crazy too. Problem started a while ago before any other problems. Had rear brake line along frame rust through which started me really getting into what was wrong. Replaced line and rear brakes complete. Problem still there. Replace front brakes complete and master cylinder. No change. Check front end. Tie rod ends, ball joints, control arm bushings all seem OK. Idler arm had minor give so replaced that. No sign of looseness in rear springs. Put trans in neutral to brake to eliminate drive train. No appreciable change. Drives smooth down road at any speed.

ok..its got to be the rotors or the rear hubs

Expert:  tims auto repair replied 1 year ago.

there is nothing else touching the pads/shoes when braking

Expert:  tims auto repair replied 1 year ago.

even with worn front end parts it should stop smooth if the rotors and hubs are true

Customer: replied 1 year ago.
Problem was the same before and after brake work. Checked runout on rotors an is at .002. Vibration is too fast and constant at differing speeds for runout or rotor thickness. I am going to try to bypass RWAL valve to eliminate it. I was an auto/truck mechanic until early 80s so not complete novice, but out of date for newer vehicles. Will get back to you later.
