abs problem with 1999 rodeo ls

I have a 1999 isuzu rodeo, about two weeks ago i braked but there was no brakes, i had to use the emergency brake also my abs light was on. this madcanic told me that my master cylinder needed replacement. he changed the master cylinder and the abs light did not go away.this cost me 279.00 for parts and 80.00 for labor. i continue to drive and when i brake there is a grabbing at the brake and also a funny sound. he then told me it seem that a abs sensor is bad. he changed the rear left abs sensor,the cost was 125.00 parts and 60.00 labor. the problem continus, i took the vehicle to the isuzu dealer today and they said i need right front wheel speed sensor, both front wheel exciter rings and needs repair short for rear wheel speed senor. cost of parts 335.00 labor 450.00 plus tax. any suggestions the mileage on my 4x4 is 97000 , v6 and it is automatic transmission and i had my brakes done about june or july 2006

Hello finechile, and Welcome to AF. This is the wrong section, I'll move this to the Rodeo section for you.

You should probably post up how many miles, what engine and transmission you have, and how long it has been since you had new brakes, so that you can get some better help.

send me the last 9 digits of your VIN# before spending anymore money
