Brake Fade!

Hey Guys, just got my 08 4 door re geared 4:56s, cold air and chip. Run 35" grabbers with brand new brakes. ran up to big bear last weekend and experienced bad brake fade when we got up the hill. Pedal spongy . Ok we let it cool down and they seemed to get better. We're able to drive around town and get down the next day. This was not an off-road trip. Was cautious and used brakes seemed fine. Was told by local mechanic in Big Bear by phone that this is common with new brakes and the got hot and glazed!? My shop will make it right, just curious on any thoughts here.

Thanks, KTM a

Sounds like pads were not broken in correctly

Did you flush out the old fluid and put in new brake fluid???

Breaking in Brakes

Find a large parking lot or somewhere where you can get to approx 60 to 70mph. Accelerate to approx 70mph and then hit the brakes hard. Do not lock them up or get into the ABS and then release when you get to about 10mph.
Do not come to a complete stop repeat until you can smell the brakes. Then take a nice drive to allow brakes to cool and then return and repeat stops. When you can smell the brakes cool them off. Never, ever, ever come to a complete stop. Repeat until you no longer smell the brakes. You may also get a few hard pedal as the brake pads off gas. Pick a road or parking lot with lots of room and nothing to hit. You have now bedded in your pads and shoes.

Now some pads say they are broken in by the manufacturer. Dont believe them.

FYI, Re: my question about brake fade. My shop told me my new shoes did not seat properly and he is replacing (at no charge) with heavier duty pads.
In hind site my first trip with new brakes was fully loaded hauling *** up mountain roads, so maybe prudent to do some around town driving for a few days before
Fist "date"!

Thanks again, KTM
