front calipers on a 2005 suzuki ignis sport

[douglas-757vo]

Hi,
all,bit of trouble with my front calipers,tokico type, bought used fronts from a breakers yard down south,arrived today Friday 01-12.
but on opening package they are bosch ones,can you fit those on to the sport,or not ?
I have an overhaul kit from big red,for the topico ones .
Can anyone help.
need car back on the road,and pistons on ones on the car are jamming on sometimes.

To be interchangeable they would need to have compatible hydraulic connectors, identical piston bore and similar stroke.

Other than that it will be obvious if they don't fit because the mounting points are different, pads are not positioned in the correct place relative to the rotor etc.

If you fit calipers with smaller diameter pistons you will get less braking effort for a given pedal pressure. The difference here is around 15%, a noticeable difference. You will also upset the front/rear balance - with smaller front pistons you will have proportionally more rear braking effort.

Fit the correct parts!
