Shimano SPD-SL issues

Wonder if anyone could help?

Been having 'un-fun' times with my shimano SPD-SL road pedal system recently whilst riding.

Essentially, my right foot feels much looser in the pedal than the left does. I use the yellow bottomed cleats which are meant to have a bit of float in them, but recently they have started to feel a little odd. The pedal tension is cranked right up to the full but they still seem to pop out really easily, with even the slightest of force laterally, where as the left is the same tension and stays in just fine.

This would usually be fine but i've been riding brakeless for the past few weeks as there is some play in my headset (which i should probably get sorted anyway) and twice now when i have pulled up with my right foot to skid i have just popped out, obviously not a brilliant scenario when coming up to junctions or down hills. Cleats have been changed, to no avail. Any ideas with the pedal other than just buying a new pair?

Any help much appreciated.

p.s. I realise that riding brakeless with plastic cleats is pretty dumb
p.p.s No 'get a brake' comments

I am fairly sure that it is just fucked because i am putting too much stress on them, but if anyone knows anything different...

Do you unclip with your right foot more often?

How old are they?

Send take/send em back to the retailer. If you can't raise the spring tension anymore and brand new cleats are still popping out then that's definitely a good enough reason to request a new pair.

Hippy - Unclip when bike is stationary with right foot first then swing my leg over and unclip left.

They are about 6 months old - only the cheap shimano jobs. Gonna see if i can have a go on some 105s and see if there is a difference...

There shouldn't be since they use the same cleats. How much lateral movement are we talkin here?

Not an enormous amount - only a little more than the float would usually allow. Because i was used to it so much before it definitely feels way more loose. The left cleat needs a reassuring amount of movement to pop out of the pedal where as the right feels like it comes out with very little movement - there is no reassuring click when you pop out like there is on the left..

I realise that was an awful description. It is literally a couple more mm.

sounds like you've worn out your pedal.
