So i went to Azusa canyon today and decided to push it just a bit. However while i was testing it out downhill, the rear brake began to smoke like crazy. I thought it was understandable, but I was driving in a canyon(really hot already). So, I was wondering if it is worth it to get the slotted and drilled rotors. A friend from RSR told me that the stock brakes are fine but my pads are wearing a little bit. Also, he told me to get steel lines. Just wanted to see what other s2k owners wnated to say

 

Do you take advantage of engine braking at all? Or are you one of these people who push in the clutch or throw it in neutral when you brake? Usually, the front brakes do most of the work and it's odd that your rear brake would be so overworked. Are your ebrake cables adjusted properly? It shouldn't matter that you were driving downhill on a hot day in a canyon. Something is not right in how you drive the car or how the car is set up.

 

slotted and drilled rotors wont really help...it's weird that it's coming from your rear breaks since they only get about 30-40% of the braking power.

I'd suggest new pads, and flush your brakes with DOT 4...

 

yeah. i was engine braking on the way down, but it was weird cause it only came from the rear right side.

 

Since the problem was unilateral, I suspect a problem with the brake caliper components or actuators. Replacing the rotors will not help. I don't think it would be the pads either, but inspect them to make sure they are not glazed or crumbling, as this may be a symptom of the issue, not a cause.

As xviper suggested, start with making sure that the hand brake cables are releasing correctly. If that's not it, it could be a number of issues: Perhaps the slide pins are not lubricated properly, there is contamination in that brake line, or the piston is not retracting properly in the bore. If it's not the hand brake cables, I suggest that you inspect the slide pins and if they are OK, flush the brake fluid. If that doesn't solve the problem, a caliper rebuild may be the solution. No matter what you do, service both sides for throughness.
