Brakes make hissing / air leak sound when pressed , possibly bad break booster?
Posted: Wed Apr 26, 2023 12:45 pm
Hey so I've got a 2014 caprice ppv making a air leak sound when the brakes are depressed. Brakes still function great, the hissing will go on seemingly forever. The issue doesn't seem critical but id like to address it obviously. At the very least its annoying. so anyways my questions are this.
-do I need to bleed the brakes to replace the brake booster?
-has anyone here done this before? I haven't found a single thread about it
-is there any documented procedure for this or am i just going to have to wing it?
-any tips and tricks regarding the booster or how to approach the issue?
If I have to bleed the brakes I'm probably going to have to take it in to the dealer as I don't have the tools or patients for bleeding the brakes on a car (I'm a motorcycle mechanic). I'm hoping I can just take some parts off and replace them but I've never owned a car with a brake booster and I'm not sure exactly how it functions in this car. Anyways i thought it would be nice if there was a thread discussing the brake booster because it does not exist on this forum yet. so any info or diagrams or tips anyone has on the subject please drop them here so we can accumulate more info regarding the brake booster system.
thanks for reading guys
