I see that the master cylinder can be purchased online for 40 to 45 dollors on 2001 Chevrolet Silverado 1500

Why are you charging 168 to much poor for the same part?

The repair shop has got to mark up parts prices, that is how they make money! You can buy a used master cyl. for that price, 40. to 45. but not a new high quility one, i,ve checked! Also labor rates are high, i agree, but the mechanic's dont work for nothing either, in fact not enough! The shop has other expenses too like: the FACILITY, garage liability insurance, 'high dollar' tool's and equipment, utility cost, shop supplies, HASMAT disposal etc. A top quality, complete mast. cyl. for that vehicle is going to cost around 130.00 (plus). You can skimp on some parts but not brakes! The shop is doing you a favor by having a real mechanic install top drawer 'BRAKE' parts since nothing will take their place when you need to STOP!!!

on line parts are the cheapest parts ever and have a really bad return policy. pay the extra and get a warrnty,its worth every penny in the long run. good luck
Do you if its part is New,Re-manufactured/Rebuilt? Sometimes its hard to believe but one gets what one pays for... So i recommend you compare Warranty (Parts/Labor),Brand because a Master Cylinder play a very important roll within the brake system of any vehicle. Good luck.
It is new with a good warranty and available from many parts dealers in that price range.
Tell me where i can buy this, 'new' complete, brake system master cylinder for the price you indicated, $40.00 to $45.00, at my door! Also the brand name.
Poor boy.
#1 quality of part #2 length of warranty
