I was bored last night so decided to have a fiddle with the R (no lewd comments please shroom! :p)
Apparently the brake pedal has adjustable free play in it, the same as the clutch pedal has (similar threaded pushrod, locknut & pedal clevis). According to the workshop manual there should be 1-3mm free play at the pedal. Mine was a fair bit more than that, presumably with almost 30 years of use and things wearing out.
So I busted out the 14mm spanner and adjusted the free play down to as close to 3mm as I could, without unscrewing the rod from the brake pedal clevis too far.
It could just be a placebo but I'm now pretty convinced that the brakes feel a lot more progressive and direct than before. Don't get me wrong, the brakes worked fine before but they just feel 'better' now. There's definitely a lot less travel on the pedal before it starts to do anything now. In fact I almost gave myself whiplash after reversing out of my driveway this morning :p
Anyone else had a fiddle with this?
