Brake Questions

[John M.]

1994 LT1 Convertible:


I am hoping a cleaning and caliper kit will correct the drag.

I am considering replacing the rotors with Power Slot Cryo Slotted Brake Rotors and pairing them with Hawk Performance HPS Performance Street Brake Pads. Both available from BuyBrakes.com

Has anyone had any experience with any of these products or seller?

Re: Brake Questions

Your 'warped rotor' may just be spots of pad material that have bonded to the rotor surface. This is very common, warped rotors are not. Any garage will have a rotary tool and fixture with abrasive pads, something like scotch brite, that will easily remove the contamination.

Re: Brake Questions

I agree with Michael. New brake pads have to be bedded in and most people don't have a clue what that means. Later, they get a pulsating from one or more rotors and buy new, only to start the process over. Get them clean, take the car out to an empty parking lot and perform a series of hard stops, gradually increasing your speed. This beds the pads and should provide long life for your roots and pads

Re: Brake Questions

Had the same problem on my 84. I cleanned the rotors installed new pad and bedded the pads in. And that took care of it.

Re: Brake Questions

John, you don't have warped rotors, at least I'd bet some $$$ on it. What the guys said above is correct though I don't bed in pads in a parking lot (you can't go fast enough). Your current discs may be OK, IF they don't have grooves in them (definitely check that rear one that's dragging). Measure the discs with a mike, the standard thickness is 0.795, and shouldn't vary by more than a half thou (0.0005). The discs can be turned down to 0.744. You can also measure the runout with an inexpensive dial indicator clamped to a jack stand, calipers off and wheel nuts holding the disc and torqued. Measure 1/2 in from the rotor edge. 0.003 is the max runout. If you have runout, you can try rotating the disc and remeasure. (While you're there, check the wheel bearing play with the dial).

Re: Brake Questions

Thanks for the info guys, I really appreciate it. Sorry it's taken so long for that response but shortly after I asked this question life kinda got in the way for a while. It started with a routine "it's time for it again" colonoscopy that revealed a possible cancerous mass. Doc said if it isn't now it will be! This was followed by a quick transverse colon resection and the following recovery time. The removed mass was tested as cancerous, but a follow-up CT scan a few days ago showed that it was caught in time and all else is clear. Sometimes ya just get lucky! This is the first time I have been back in this forum since the beginning of that adventure, and now that my gut can actually bend again maybe I can drop down and get into that Corvette and finally get it out of storage. That might also be contingent on all this rain being dumped on us this year too, but when I do get her out I plan to make good use of the advice you have given me here.

Thanks again, and Save the Wave ............... JG Mattson

Re: Brake Questions

John,

Glad you are OK and back on the road.

As for your brake problem. After purchasing a 96 with 93thousand miles I discovered it had no brakes to speak of! After replacing the rotors with Delco grooved and drilled rotors and Delco Ceramic pads I had great brakes. Now after 240thousand miles and replacing the pads only once I still have great braking power. The 96 Corvette is a great driving machine that will service your needs for thousands of enjoyable miles.
