I have a 1997 K1500 Suburban with about 85k miles on it. I have had to
replace the rotors twice in the last year. I was hoping someone might know
of a good after-market rotor to use so that I might change them less
Second, I have this pulsing like thing happening in the electrical system.
All the lights (head,tail,dash,dome etc) pulse in and out while the engine
is running. Not to the on/off point but just a slight pulsing that I notice
while driving at night.
I will be replacing the rotors for the first time on my 97 Tahoe with
PowerSlot crossdrilled rotors and Hawk Brake Pads all for around $225. I
have been replacing front pads like every two years since I bought it new
........ I have yet to replace the rear shoes and the drums are still in
great shape ....
The pulsing sounds like the alt. getting ready to give up .....
I would buy the factory rotors again. The brakes on my 1996 Suburban 1500
with Turbodiesel are still original at 91000 miles. In fact, at last month's
dealer tire rotation, both the shoes and pads had still more then 6
millimeter thickness. Good for another 30 k or so!
As to pulsing lights, check for an intermittent power consumer staying on,
e.g. rear window defroster or glow plugs.
Rotors can be a pain. What is happening to them that causes the need for
replacement? As for the pulsing lights, it could be a bad connection to
your alternator,battery or grounding for either of them, Could also be a bad
alternator. Is it a steady pulse (alternator) or a varied one like hitting a
bump or turning left/right(connection)?
The rotors are warping. I have read that this is an issue with these years,
but, I was hoping someone might know of a good aftermarket setup.
The pulsing is constant, speeds up with the enging and slows down with the
engine. Took it in and no-one can figure it out.
have you checked to see if your back brakes even work? the drums on the
back were marginal at best and usually you only notice they're not working
by eating up brake pads and/ or warping your front rotors.
