I need to replace the front brake calipers but can not find the same brand as the rear. Does this affect the car in any way or should i keep on looking for the same brand.
If you really can’t find the original make then you should at least have a pair of the same make of caliper at the front, even if they are a different make to the rear.
Do make sure that the pipe fittings match - experience has shown that there can be minor differences that are sufficient to cause problems and you do not want sudden problems with brakes. And if there are multiple circuits make sure of the connections so the circuits stay as they should.
Also make sure the pads are matched axle sets.
Otherwise there might be performance differences that surprise you,
