That's very little data, you shouldn't be experiencing such an ordeal.
Just to see if we can lure Oracle to do something different please try altering a little your session environment by adding commands below before your CREATE MATERIALIZED VIEW command...
alter session set db_file_multiblock_read_count = 64;
alter session set sort_area_retained_size = 250331648;
alter session set sort_area_size = 250331648;
alter session set sort_direct_writes = true;
if it doesn't work, you can try to pre-build your MVIEW table.
1- Create table brands_trans_all_v with all columns you need.
2- Refurbish you mview creation script to insert into table brands_trans_all_v all the data you want to have in your MView
3- Issue a create materialized view brands_trans_all_v on prebuilt table... command
At this point you should be the happy owner of mview brands_trans_all_v
