If your parking brake isn't working properly, it's likely due to one of these issues requiring professional attention:
* Worn brake pads: This is the most common cause. Worn rear pads mean less contact with the rotor, reducing braking power. Replacement is necessary.
* Internal caliper issues: The parking brake mechanism within the rear calipers could be seized, broken, or simply worn out. This usually requires caliper rebuild or replacement.
* Contaminated brake system: Fluid contamination can affect braking performance, including the parking brake.
* Cable damage (unlikely, but possible): Though less likely given the Integra's setup, a severely damaged cable connecting the parking brake lever to the calipers could be a factor. This usually manifests as one side not working.
In short: You should not attempt to adjust the parking brake yourself. Take your Integra to a qualified mechanic or brake specialist. They have the tools and expertise to diagnose the problem and perform the necessary repairs or replacements. Improper adjustments could damage your brakes and lead to dangerous driving conditions.
