FASTFREDDY Posted September 18, 2008 Share Posted September 18, 2008 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? Fred Link to comment Share on other sites More sharing options...
raceboy Posted September 18, 2008 Share Posted September 18, 2008 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. Raceboy Link to comment Share on other sites More sharing options...
docc Posted September 18, 2008 Share Posted September 18, 2008 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. Link to comment Share on other sites More sharing options...
nose2wind Posted September 18, 2008 Share Posted September 18, 2008 Check steering head Bearings for looseness. I had this condition but it was more of a chatter! Good luck D Link to comment Share on other sites More sharing options...
gavo Posted September 20, 2008 Share Posted September 20, 2008 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 Link to comment Share on other sites More sharing options...
jrt Posted September 21, 2008 Share Posted September 21, 2008 +1 This is what worked for me. I used a square plumbing tool to rotate the buttons when I lubricated them. Check them all. 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.

FASTFREDDY Posted September 22, 2008 Author Share Posted September 22, 2008 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. Fred Link to comment Share on other sites More sharing options...
