I'm writting my dissertation and this is the last adjustment that is still remaining

I'm using a document class called abnt.cls written from the guys of TexBR. This class is based in the REPORT class.
I already customized the toc to indent everything left using the commands below:
Code: Select all
\usepackage[titles]{tocloft}
\renewcommand{\cftsecindent}{0 em}
\renewcommand{\cftsecnumwidth}{1.9 em}
\renewcommand{\cftsubsecindent}{0 em}
\renewcommand{\cftsubsecnumwidth}{2.8 em}
\renewcommand{\cftsubsubsecindent}{0 em}
\renewcommand{\cftsubsubsecnumwidth}{3.2 em}
The toc creates spaces between each entry. It also creates a bigger blank space between the last entry from a chapter and the next chapter entry.
I'd like to reduce space between entries and space between last entry and next chapter to a simple space.
Can anyone help me out with that?
Thanks in advance,
:Luiz.
