Ok need some help or even a link to a website on stripping these type of pedals down. Got a horrible creaking noise from lower bracket area on my Langster. I thought it was worn chain/rings etc but not convinced they would be this noisy? So closer examination has allowed me to witness some play on the left pedal bearing, which I reckon could be the source? The pedals are Shimano R540 SPD-SL, and I suppose they are cheap enough to buy but if they are easily taken apart surely a wee grease up and bearing adjustment maybe all they need!
