This one of the biggest annoyance for a lot of prefacelift car owners the dreaded clicking and grating sound.Honda have addressed the design and manufacturing issues arisen from the vendor. There are two way of fixing this problem the unofficial and the preferred method and the other method which is a workaround and not a complete solution. I have been told by reliable sources the 2007 production models do not have this issue they have got the revised modified part fitted from the factory. This is applicable to both petrol and diesel cars up to production models 2006. What are the Symptom ? Clicking or grating noise when the clutch pedal is depressed. Very noticeable when stuck in stop and start traffic conditions, the constant use of the clutch pedal causes the friction. What is the Cause? There are three possible causes: 1. Interference of internal parts in the clutch master cylinder. 2. Metal contact caused by a lack of grease where the clutch pipe connector is coupled. 3. Interference due to remaining burr inside the master cylinder where the clutch pipe connector is coupled. The preferred fix 1. The spring shape inside the clutch master cylinder has been changed. 2. Grease application has been increased. 3. The deburring process has been improved. The modified part number is 46920-S7A-A01 when changed it is supplied with a special rubber grease and new o rings and brackets for the rubber hoses and metal pipe unions. It is recommended these hoses and metal pipe ends are lubricated with the grease supplied in the kit. This is the source & cause of the noise. The workaround. If owners don’t want to spend money on the new master cylinder they can lubricate the push rod which connects the master cylinder to the clutch pedal. My moving the pedal up and down you want to get rubber grease into the crevices. Ensuring the rod is lubricated at the source with the master cylinder. Please note due to constant use the heat builds up on the rod will dry out this grease. It will be a repetitive process again to stop the noise. Warning Do not lubricate the push road with another grease than Molokote G-Rapid plus. Don’t not use general purpose or even WD40 on it, it will make things worse causing the rubber part to swell. TIP. Another important measure to ensure a perfectly and smooth operation is to change the brake fluid in the clutch master cylinder. I personally change it every year without fail. A How to and DIY will follow soon.
