Having problems with your Cars & Trucks ?
After new brakes, grinding noise in rear. repair guy says need $600.00 proportion valve job! Already had new one 3 years ago.
\015 There was no noise before the car went in for brakes. We had front disc brake rotors and pads put in as well as rear, and shoes all around. New master cylinder, a brake hose, and front lt reb calp (whatever that is). The totyal came to $914.09. We picked up the car and took a drive a few days later. There was a slight, soft rubbing noisde. Husband said when he went to get the car they were still bleeding the brakes (they had the car for 3 days). He figured the brakes were not fully bled. He took the car back and now they say we need a proportioning valve for $600.00 but it was replaced only 3 years ago. They said come back when we can afford it and that the car is perfectlyafe since all other brakes are brand new. This is 3 weeks later and the noise is a loud grinding that comes and goes. Sounds like something is getting stuck. Does all this sound right? Should I trust this repair and quote?\015
The grinding sound could be a brake pad installed wrong or backwards.There should not be any grinding what so ever.There is a serious problem.I would take it to a shop or dealership you can trust and have it check out.
Doesn't sound right at all! I would definitely not trust their assessment that the prop. valve is at fault. If they are unwilling to take the car back and investigate for free (and they should, given that the noise only started after new brakes were installed), then take it to another mechanic ASAP.The valve is designed to keep the rear brakes from locking up before the front brakes take hold. I don't see how it could cause the noise you describe. Sounds like they didn't get something back together right. Have someone look at it, and show them your receipt so they can verify all the new parts were actually installed. I would do it before the grinding causes further damage.
