Disc brake adjustment?

[Dibs]

I have a Boardman Cx and recently the disc brakes have lost their bite and I am pulling back quite far on the levers to stop.

I have done about 900 miles on it since February, so will a quick adjustment work or new pads required.

If adjustment - is it the adjusters at the levers that need tweaked?

Cable pull or hydraulic ?

If cable pull you can adjust at either end.

Cable! Thanks. Will try that!

You can always pull a little more through at the calliper if there is not enough adjustment. Also, check the pads are aligned to the disc. It's easy to re-position the calliper by undoing the mounting bolts.

I'd look at adjusting the pad wear by turning the pad adjustment screws, rather than jibbling with the cable adjustment. Cable discs tend to have one fixed and one floating pad, and as the pads wear they need moving closer to the disc again. When you pull the lever, the floating pad is pushed against the disc and deforms it towards the fixed pad, so the fixed pad , at least, needs to be very close to the disc.

Some excellent you tube videos on how to adjust various cable disc set ups. Easy once you know how.

Unless you have trp spyres which have dual pistons and both pads move inwards when you pull the lever........single pistons are so 1980's

And i found the single pull ones on my mtb a right pita to keep adjusted .

You need to loosen off the brake cable, unscrew the caliper bolts and take off the calipers. Then throw them in the bin. Then buy some TRP Spyre calipers and fasten those on in their stead.

This may seem like a more drastic solution than simply turning the pad adjuster a couple of turns, but in the long term it will save you an immense amount of time and frustration and you will be glad of this advice.

Cheers.
