brake shudder

[FASTFREDDY]

Hey y'all,

 

I just noticed today that when I come to a sto and get to just under 20mph my front brake shudders. very noticeable. i checked the pads and they are very good.

Got any ideas?

I assume it's the front brakes that are giving the problems.

 

Check the discs for warpage, possibly caused by overheating. A good way to tell is look for any discolourations (blueing). More accurate method is using a dial gauge to check for Flatness....is that a word??

 

Also check to make sure the caliper and disk fasteners are tightened to the appropiate torque specs.

 

Hope that helps a bit.

The rotors are "semi-floating." Which means they semi "do not" float. Lubricate the buttons with a penetrating oil like Break-Free CLP and tap the rotor around a bit with a mallet. Wipe off any excess oil and see if the shuddering doesn't improve.

 

Consider , also, cleaning the pads with a good brake cleaner and bleed the system well.

Check steering head Bearings for looseness.

 

I had this condition but it was more of a chatter!

 

Good luck

take the pads right out of the caliper and check and clean. I had a pad seperate from its backing plate and cause a terrible vibration but could not see it until I removed the pads

This is what worked for me. I used a square plumbing tool to rotate the buttons when I lubricated them. Check them all.

Well I took the pads out and cleaned them with brake cleaner. Reinstalled and no shudder. Musta had some gunk on a pad. Thanks for all the advice.
