I have a 2002 Shogun LWB. When the brake peddle is depressed

Resolved Question:

I have a 2002 Shogun LWB. When the brake peddle is depressed lightly the brakes give way haltingly, similar to when the antilock system is deployed. When pressed more heavily the brake acts as normal. Can you suggest what is wrong?

I would love to help but i am having a hard time understanding your symptoms.

 

Are you saying under light braking you get the brake then release type feeling associated with ABS or are you saying barely braking causes a harsh jerking stop?

Customer: replied 3 years ago.

Yes, Light braking causes the feeling like the ABS anti wheel lock system is working. You feel you are braking then its released then you are braking again, this is repeated until you stop. If however you press hard on the brake, the brake operates normally.


Hope that clears any confusion.

Yes, that helps significantly.

 

Assuming that you are not getting any ACTUAL ABS activation, meaning you don't HEAR the pump running (buzzing), then I would start by inspecting the front rotors and pads for any warping or obvious defects.

 

The symptom your referring to would be called a brake pulsing and is usually only caused by warped or damaged rotors, but can also be caused uneven braking from a sticking slide pin (although very uncommon to pulse).

 

So In my opionion, start with the front brake inspection and go from there.
