I'm looking for any publicly available RNA-seq data sets containing RNA-seq data related normal brast tissues.
You can explore GEO databases and choose high-throughput option.
The NCBI SRA (Short-Read Archive) database has many Next Generation Sequencing datasets, most of which are from RNA-Seq studies. You can download the FASTQ files using the sra-toolkit, and some of the records also have links to the GEO databases cited by Albolfazi Bahrami.
As already pointed out GEO will contain a lot of data but the other major option is arrayExpress at EBI. https://www.ebi.ac.uk/arrayexpress/
RNAseq from normal breast is also available from the gtex portal.

I would also recommend "MyGenomeSpace" which has links to repositories and different free gene analysis and visualization tools. I attach a partial screen view. The "IGV" is the one I use to load RNAseq data to visualy compare gene expression between different experimental groups http://www.genomespace.org
UPDATE: Unfortunately this page was closed due to lack of funding (yes the Broad Institute at MIT, the same that patented CRISPR has no money to keep a webpage that serves the scientific community). The individual programs are still available (you can google them)
The easiest and the best way in my opinion is :
first search your subject in GEO datasets
second from there you can access to the project number and SRP number of your datasets of interest
then add it or download it with what ever tools you use for analysis
I agree with Abolfazl Bahrami's suggestion to search GEO for studies that may be of interest and collect the GEO series or SRA project accession numbers. Then you can search for those studies at databases such as:
- Recount https://jhubiostatistics.shinyapps.io/recount/
- ArchS4 https://amp.pharm.mssm.edu/archs4/
- DEE2 http://dee2.io/ (I am the maintainer of DEE2)
Best of luck with your project
