Brakes sticking on
Posted: Thu Jun 05, 2008 11:22 am
I have just overhauled the Lockheed single line brake booster in my Rover P6B, and now to my dismay the brakes are not releasing after an application of the pedals.
The harder the application, the tighter they lock.
I have had a booster do the same but to a lesser degree some years ago. The brakes would stick only on light applications. Hard applications would see no problem. On that occassion, I returned to booster and received a replacement.
This booster was used in the car from 1990 till 1998. The slave cylinder had been resleeved prior to 1990. I have now rebuilt this booster.
I fitted a genuine Lockheed kit, and followed the instructions to the letter, comparing and cross referenceing to ensure no mistakes were made.
I did notice that both the piston assembly within the slave cylinder and especially the air contol piston after fitting the new rubber seals were very tight within their respective bores. The air contol piston especially so!
If this air contol piston were to stick, would that result in the brakes remaining on after an application?
Any help will be greatly appreciated.
