I am thinking of putting in new discs and wheels on my mtb.

Is it a straight swap or do I need to adjust calipers etc. The same disc size is going on.

thanks

    You will probably have to adjust the calipers.

    You'll probably find you need to adjust the lateral position of your calipers as the rotor will probably not be in exactly the same place along the axle. With the bike on a stand or upside-down spin each wheel to check it spins freely. If it doesn't loosen the two bolts on the caliper (remember lateral ones so that the caliper can now move along the direction of the axle) and spin the wheel. It should now spin freely since the caliper will now be in the right position. Keeping it in this position the bolts can now be tightened.

    Yes, your brake instructions! Download the manual, or see Park Tools.

    yes I have 2 sets of wheels both built on Hope Pro 2s, same Avid rotors but clad in different tyres.

    I swap them over q frequently but always have to adjust the calipers, 1 end I think the front is ok, rear one always a bit out.

    Its good practice anyway to clean everything up while you are doing it.

    Theres a good Youtube vid of it.

    you could alsoloosen the 2 lateral bolts off as mentioned above and then pull the brake levera couple of times then hold it on whilst tightning the bolts back up to get the calipers and discs aligned
