    We introduce a Brauer type algebra BG(Î¥)B_G (\Upsilon) associated with every pseudo reflection group and every Coxeter group GG. When GG is a Coxeter group of simply-laced type we show BG(Î¥)B_G (\Upsilon) is isomorphic to the generalized Brauer algebra of simply-laced type introduced by Cohen, Gijsbers and Wales ({\it J. Algebra}, {\bf 280} (2005), 107-153). We also prove BG(Î¥)B_G (\Upsilon) has a cellular structure and be semisimple for generic parameters when GG is a dihedral group or the type H3H_3 Coxeter group. Moreover, in the process of construction, we introduce a further generalization of Lawrence-Krammer representation to complex braid groups associated with all pseudo reflection groups.Comment: This paper is an improved version of my last one "Algebras associated with Pseudo Reflection Groups: A Generalization of Brauer Algebras", with many mistakes corrected and new contents adde
