1989 Honda Accord Shakes when braking

Hi there,

Thank you for the donation,

When you are breaking, is the vibration in the body or the steering, and can you feel any pulsation in the brake pedal?

Hi there, start with having the rear wheels and tyres check for faults, body vibration under braking is usually here, and get the booster checked as well as this may be the cause of the hard /soft pedal issue,

AS I said, body vibration is generated at the rear wheels, get that checked first then we can look at the steering vibration.

OK back to basics,

Any vibration felt in the steering must be transmitted through the front wheel, the vibration is due to an out of balance rotation, so we must check Front wheels, front brake rotors, wheel bearings, drive shafts, looses or defective steering, serious alignment problems due to bent frame or mis aligned sub frame, bent steering arms, an alignment will pick up and bent steering and body alignment problems, as you know wheel problems and drake issue can be the cause of around 80% of this type of vibration, do not fall into the trap of presuming what has been checked is OK, I would start again, and make sure that the mechanic is qualified and his equipment is calibrated and not giving false readings, go back to basics and let me know how you get on.

There will be nothing else that will cause a steering vibration under braking. About the only other thing that I can think of would be miss alignment of the brake rotor on the hub, may be there is some foreign matter between the rotor and the hub? The generation of the vibration under braking is directly related to rotors, pads & calipers as if any other item was at fault you would normally have this vibration all the time. With out experiencing this first hand, I am at a disadvantage so I can only suggest what I feel is the cause under normal operation conditions.
