So I jacked up my car in the porch and opened the front wheel. Silicone was applied on the front right brake caliper as well as the Brembo cover. But when I tried to position the Brembo cover it neither fitted the vertical face nor the horizontal face of the brake caliper.
Since Brembo covers were generic not specifically made for the reborn's brake calipers.
But it occurred to me that since Brembo covers only have face value a perfect fit on the brake caliper isn't necessary.
So, by hook or by crook I chose an optimum position for the Brembo cover on the caliper. I tried to support the Brembo cover with my hand for 15 minutes but it would drop as I came to know that silicone takes around 24 hours to settle!
So I tried to hold it with insulation tape temporarily and tried to close the wheel :S
But when I tried to screw the lugs I found that the Brembo cover is not allowing the wheel to sit on the hub properly.
The Brembo cover was touching the rim's spokes.
