Great day and Andy’s car is a great example - he’s far too harsh on it when he talks about it online
I’m still getting my gopro stuff together but will write something up soonish. We were hoping to get some laps running astern of each other so that we could get gopro footage of each car but the track was pretty crowded and it wasn’t easy to share a piece of tarmac! The only time we pulled it off, Andy had his tank slapper above 2 corners later so that was that
I took my car upto Jonny at https://www.performance-autocare.co.uk/ on Saturday. Its fantastic he is open Saturdays as I am often losing money taking the car to a garage as I am a contractor and it also meant I got to spend some time with Wife Bond!
Rear discs , pads and fluid was changed out ( Motul RBF 660 ) but not the supercharger belt. Reason being is Jonny spotted the bottom pulley bolt was almost out! Its no wonder the belt was squeaking, the pulley was walking side to side! This has been corrected now.
I drove the car back home and it feels super smooth now, but I have managed to pick up some scoring on both front pads which is a bit frustrating.
Something isnt quite right on my nearside front pad. After a short while I get a clack , clack , clack sound. I can only assume its the pad touching the disk and the vanes. If I press the brake ever so slightly it goes, then returns 30 seconds later.
Braking feels fine, nothing is pulling to the left or right.
Ill whip off* the front wheel tomorrow and disassemble the caliper / pad and look for any abnormalities.
no whipping at the car is low and I have to drive up onto some wooden blocks to be able to get my low jack under …
Fairly common I think, not sure if the caliper tolerances are slightly off for the quoted pad size or what but I’ve had pads from various manufacturers clack around like that across both my Lotus’. It seems like the disc rotation is able to lift the pads up slightly, then they drop down, rise up, repeat. If you can replicate it easily by slowly going back and forth on your drive then that’s probably it.
You can get anti-rattle buffer pads to put on the slider plates within the calipers (think EP does them at least) but I find they don’t stand up to heat and hard use very well. Generally I find the pads eventually seat themselves home with enough clugged up brake dust etc
Yeah I struggle to put a pattern to it, it’s definitely worse after I give the calipers a good clean and fit fresh pads then they seem to settle in a bit. I assume dust and road grot just pads them out a bit!
Also try gently bending the clip spring thing so that it exerts more force onto the pads, maybe that relaxes a bit when it gets hot?
